linked list in data structure
This document discusses data structures and linked lists. It provides definitions and examples of different types of linked lists, including:
- Single linked lists, which contain nodes with a data field and a link to the next node.
- Circular linked lists, where the last node links back to the first node, forming a loop.
- Doubly linked lists, where each node contains links to both the previous and next nodes.
- Operations on linked lists such as insertion, deletion, traversal, and searching are also described.
single linked list
This document discusses the implementation of a single linked list data structure. It describes the nodes that make up a linked list, which have an info field to store data and a next field pointing to the next node. The document outlines different ways to represent linked lists, including static arrays and dynamic pointers. It also provides algorithms for common linked list operations like traversing, inserting, and deleting nodes from the beginning, end, or a specified position within the list.
Data Structures - Lecture 9 [Stack & Queue using Linked List]
This document discusses implementing stacks and queues using linked lists. For a stack, elements are inserted and removed from the head (start) of the linked list for constant time operations. For a queue, elements are inserted at the head and removed from the tail (end) of the linked list, requiring traversing to the second last node for removal. Implementing stacks and queues with linked lists avoids size limitations of arrays and uses dynamic memory allocation.
Heap sort
The document discusses heap sort, which is a sorting algorithm that uses a heap data structure. It works in two phases: first, it transforms the input array into a max heap using the insert heap procedure; second, it repeatedly extracts the maximum element from the heap and places it at the end of the sorted array, reheapifying the remaining elements. The key steps are building the heap, processing the heap by removing the root element and allowing the heap to reorder, and doing this repeatedly until the array is fully sorted.

AVL Tree
An AVL tree is a self-balancing binary search tree that guarantees search, insertion, and deletion operations will take O(log n) time on average. It achieves this by ensuring the heights of the left and right subtrees of every node differ by at most one. When an insertion or deletion causes a height imbalance of two, rotations are performed to rebalance the tree.
Applications of stack
The document discusses applications of stacks, including reversing strings and lists, Polish notation for mathematical expressions, converting between infix, prefix and postfix notations, evaluating postfix and prefix expressions, recursion, and the Tower of Hanoi problem. Recursion involves defining a function in terms of itself, with a stopping condition. Stacks can be used to remove recursion by saving local variables at each step.

Circular link list.ppt
This document provides information on circular linked lists including:
- Circular linked lists have the last element point to the first element, allowing traversal of the list to repeat indefinitely.
- Both singly and doubly linked lists can be made circular. Circular lists are useful for applications that require repeated traversal.
- Types of circular lists include singly circular (one link between nodes) and doubly circular (two links between nodes).
- Operations like insertion, deletion, and display can be performed on circular lists similarly to linear lists with some adjustments for the circular nature.
Sparse matrix and its representation data structure
The document discusses sparse matrices and their efficient representation. It defines a sparse matrix as one with very few non-zero elements, so representing it as a standard 2D array wastes space storing many zero values. More efficient representations of sparse matrices include storing only the non-zero elements and their indices in a triplet format, or using a linked list structure with one list per row containing (column, value) node pairs. Examples of each approach are provided.
RECURSION IN C
Functions allow programmers to break programs into smaller, reusable parts. There are two types of functions in C: library functions and user-defined functions. User-defined functions make programs easier to understand, debug, test and maintain. Functions are declared with a return type and can accept arguments. Functions can call other functions, allowing for modular and structured program design.

Data Structure (Queue)
Queue is a first-in first-out (FIFO) data structure where elements can only be added to the rear of the queue and removed from the front of the queue. It has two pointers - a front pointer pointing to the front element and a rear pointer pointing to the rear element. Queues can be implemented using arrays or linked lists. Common queue operations include initialization, checking if empty/full, enqueue to add an element, and dequeue to remove an element. The document then describes how these operations work for queues implemented using arrays, linked lists, and circular arrays. It concludes by providing exercises to implement specific queue tasks.
Data structures using c
The document discusses various data structures and their classification. It begins by stating the objectives of understanding how data structures can be classified, basic data types and arrays, and problem-oriented data structures used to solve specific problems. It then defines key terms like data, information, and data structures. It describes primitive and non-primitive, linear and non-linear data structures. It also discusses basic and problem-oriented data structures like lists, stacks, queues, and trees. It provides examples and applications of different data structures.
Queue ppt
The document discusses different types of queues, including simple, circular, priority, and double-ended queues. It describes the basic queue operations of enqueue and dequeue, where new elements are added to the rear of the queue and existing elements are removed from the front. Circular queues are more memory efficient than linear queues by connecting the last queue element back to the first, forming a circle. Priority queues remove elements based on priority rather than order of insertion. Double-ended queues allow insertion and removal from both ends. Common applications of queues include CPU and disk scheduling, synchronization between asynchronous processes, and call center phone systems.
Lec 17 heap data structure
The document discusses heap data structures and their use in priority queues and heapsort. It defines a heap as a complete binary tree stored in an array. Each node stores a value, with the heap property being that a node's value is greater than or equal to its children's values (for a max heap). Algorithms like Max-Heapify, Build-Max-Heap, Heap-Extract-Max, and Heap-Increase-Key are presented to maintain the heap property during operations. Priority queues use heaps to efficiently retrieve the maximum element, while heapsort sorts an array by building a max heap and repeatedly extracting elements.
Pointer in c
Pointer is a variable that stores the address of another variable. Pointers in C are used to allocate memory dynamically at runtime and can point to data of any type such as int, float, char, etc. Pointers are declared with a * before the variable name and are initialized using the address operator &. Pointers can be used to pass arguments to functions by reference and can also point to elements within structures.
2. Array in Data Structure
An array is a list of homogeneous (similar data type) elements stored in contiguous memory locations. Elements are accessed via an index. One dimensional arrays use a single subscript, while two dimensional arrays use two subscripts to reference an element. Arrays can be initialized during declaration. The size of an array is calculated as upper bound - lower bound + 1. Elements of arrays can be traversed, inserted, or deleted. Two dimensional arrays can be stored in row major or column major order, affecting the calculation of element addresses. Multidimensional arrays generalize this to any number of dimensions.
Stack
This document discusses stacks and their applications. It defines a stack as a Last In First Out (LIFO) data structure where newly added items are placed on top. The core stack operations of PUSH, POP, and PEEK are described. An array implementation of stacks is presented and animations demonstrate push and pop operations. Applications of stacks like checking for balanced braces, converting infix to postfix notation, and postfix calculators are explained with examples. Pseudocode provides an algorithm for infix to postfix conversion using a stack.

Specific data structures like arrays, stacks, queues, linked lists, trees and graphs are introduced. It provides examples of contiguous structures like arrays and structures, as well as non-contiguous structures like linked lists.
File in C language
A file is a collection of related data that a computer treats as a single unit. Files allow data to be stored permanently even when the computer is shut down. C uses the FILE structure to store attributes of a file. Files allow for flexible data storage and retrieval of large data volumes like experimental results. Key file operations in C include opening, reading, writing, and closing files. Functions like fopen(), fread(), fwrite(), fclose() perform these operations.
Hashing in datastructure
The document discusses hash tables and hashing techniques. It describes how hash tables use a hash function to map keys to positions in a table. Collisions can occur if multiple keys map to the same position. There are two main approaches to handling collisions - open hashing which stores collided items in linked lists, and closed hashing which uses techniques like linear probing to find alternate positions in the table. The document also discusses various hash functions and their properties, like minimizing collisions.
Linked list
Linked lists are linear data structures where elements are linked using pointers. The three main types are singly, doubly, and circular linked lists. Linked lists allow dynamic memory allocation and fast insertion/deletion compared to arrays but slower access. A linked list contains nodes, each with a data field and pointer to the next node. Basic operations on linked lists include insertion, deletion, traversal, and search. Doubly linked lists include pointers to both the next and previous nodes.

Sorting techniques
Insertion sort works by scanning an array from left to right and inserting each element into its sorted position in the previously sorted left portion. Quicksort works by partitioning the array around a pivot value, recursively sorting the left and right partitions, and combining the results. It chooses a pivot element and rearranges the array such that all elements smaller than the pivot are to its left and larger elements to its right.
Insertion and Redix Sort
The document describes the insertion sort algorithm. It works by scanning an array from the first element to the last, inserting each element into the proper position in the previously sorted portion of the array. It also describes the quicksort algorithm, which works by partitioning the array around a pivot element and recursively sorting the subarrays.

An array is a collection of homogeneous data elements stored in contiguous memory locations. Arrays can be one-dimensional, containing elements accessed via a single index, or multi-dimensional, containing elements accessed via multiple indices. Elements in a one-dimensional array are stored sequentially in memory. Multi-dimensional arrays can be stored in row-major or column-major order, affecting how element locations are calculated. Common array operations include traversal, insertion, deletion, sorting, and searching of elements.

The document discusses arrays in data structures using C programming language. It defines what an array is and describes different types of arrays like one-dimensional, two-dimensional, and multi-dimensional arrays. It also explains array operations such as insertion, deletion, traversal, reversing, sorting, and searching. Additionally, it covers merging of arrays, arrays of pointers, and using arrays to represent polynomials.
DATA STRUCTURE CLASS 12 COMPUTER SCIENCE
Arrays, stacks, queues, and linked lists are common data structures in computer science. Arrays allow direct access to elements but have fixed size, while linked lists can dynamically grow and shrink but require traversing nodes sequentially. Stacks follow LIFO (last in first out) and queues follow FIFO (first in first out) ordering for inserting and removing elements. Linked lists store data in nodes that link to the next node, allowing efficient insertion/removal anywhere in the list. Common operations on these structures include push/pop for stacks, enqueue/dequeue for queues, and insert/delete nodes for linked lists.

The document discusses different data structures and their properties. It explains that data structures can be linear or non-linear. Linear data structures like arrays have elements arranged in a sequence, while non-linear structures like trees and graphs do not. It then focuses on linear data structures and their representation in memory using arrays and linked lists. Key operations on linear structures like traversal, search, insertion and deletion are also summarized.
List - Operations and Implementation
This document discusses lists and their implementation. It describes static and dynamic lists, with static lists having fixed size and storing elements in an array, while dynamic lists can grow and shrink as nodes are linked together. It also covers array implementation of lists, including how to insert and delete nodes at a given position. Operations on static lists have complexity related to list size, while dynamic lists can grow and shrink as needed. The document also discusses using a list to implement a linear queue, with insertion only at the rear and deletion only at the front.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

Array operations
- 2. It Is An Ordered List, Which Consist Of A Fixed Number Of Homogeneous Data Items (Elements).An Array Is A Primitive Data Structure. These Elements Are Stored In Successive Memory Locations According To Size Of Data Type. Array Is Also Referred As Set Of (Index , Value).
- 3. (index) A[0] A[1] A[2] A[3] A[4] A[5] A[MAX -1] 10 5 46 2 100 97 ... Data element value
- 4. The Insert Operation Is Performed By Shifting All The Elements One Position Ahead From Index iTo N-1 Where i Is The Specified Index For New Element Is To Be Inserted. And Adding The New Element To The Array At The Specified Index Position.
- 5. For example, index for insertion is i=2 and new element is 17 with N=6. the MAX is the size of the array A. A[0] A[1] A[2] … A[N-1] A[MAX-1] 10 5 46 2 100 97 … Insert index position Move All Elements From Insert Index Position I N-1 Towards Right By One Position A[0] 1 2 3 4 5 A[6] A[MAX-1] 10 5 46 2 100 97 … Insert Index Position
- 6. A[0] 1 2 3 4 5 A[6] A[MAX-1] 10 5 46 46 2 100 97 … Insert index position Shifted elements
- 7. Now, insert (store) new data element 17 at given index position 2: A[0] 1 2 3 4 5 A[6] A[MAX-1] 10 5 17 46 2 100 97 … Inserted element For Every New Element Inserted The Number Of Elements I.E N Should Be Incremented By 1. If N= Max-1 Then Array Is Full And Insertion Operation Cannot Be Performed As There Is No Space For New Element In The Array.
- 8. The delete operation will delete the element at specified element index from one-dimensional array. The deletion operation performed by shifting all the elements one position before from index i=1 to N-1 where i is the index of element to be deleted. A[i] = A[i+1], for all i to N-1 . This shifting causes overwriting of the said element with element at next index position.
- 9. For example, For an array N=7 and index position for deletion is i=3 and maximum array size as MAX. A[0] 1 2 3 4 5 A[6] A[MAX-1] 10 5 17 46 2 100 97 … Delete Index Position Now , Shift All Element From Index 4 To 6 One Position Before As Below: A[0] 1 2 3 4 5 A[6] A[MAX-1] 10 5 17 46 2 100 97 … Element At Index 3 The Array After The Shifting Backward Is:
- 10. A[0] 1 2 3 4 A[5] A[MAX-1] 10 5 17 2 100 97 97 … Last element of array The element 46 is deleted from the array. After every delete operation the number of elements N should be decrement by 1. if array is empty , the deletion operation cannot be performed .
