Lecture Note-2: Performance analysis of Algorithms
The execution of an algorithm requires various resources of the computer system to complete the task. The
performance of algorithms depends on the use of these resources. The important resources which contribute
to the efficiency of the algorithms are the memory space and the time required for successful execution of
algorithm. The efficiency of an algorithm is measured in terms of the time and the space required for its
execution therefore analysis of algorithms is divided into two categories
Algorithm
An algorithm is a well-defined procedure for solving a problem through a series of unambiguous instructions. The word derives from the name of mathematician Mohammad Ibn-Musa-al-Khwarizmi. An algorithm must have specified input and output, be definitive, effective, and finite. Common algorithm types include recursive, backtracking, divide-and-conquer, dynamic programming, greedy, branch-and-bound, brute force, and randomized algorithms. Examples provided include algorithms for making brownies and calculating student grades.

Algorithm and flowchart2010
An algorithm is a step-by-step process for solving a problem or completing a task. There are two main tools used to document algorithms: flowcharts and pseudocode. A flowchart is a graphical representation of an algorithm that uses standardized symbols to show the sequence of steps, while pseudocode specifies the algorithm steps using natural language. The five steps in using a computer as a problem-solving tool are: developing an algorithm and flowchart, writing the program code, entering the program into the computer, testing and debugging the program, and running the program to obtain results.
What is an algorithm?
An algorithm is a set of steps to accomplish a specific task or solve a problem. It has a well-defined sequence of steps, will produce an output, and will eventually terminate. An algorithm describes the precise steps to solve a computational procedure from an input to an output in a finite number of steps. Examples of algorithms include step-by-step directions for driving to a friend's house or brushing your teeth.

Ic lecture6 architecture and algo
The document defines algorithms and discusses their importance. It provides three definitions of an algorithm, including a precise sequence of unambiguous and executable steps that terminates in a solution. Algorithms are useful because they allow problems to be solved repeatedly without needing to rediscover the solution each time. The term "algorithm" derives from the title of a 9th century book by Muhammad al-Khwarizmi, and his principle was to break problems into simple subproblems that are solved in order. An example algorithm for decimal to binary conversion is provided. Algorithms must have a precise, unambiguous, and terminating sequence of steps.
Algorithm and Flowcharts
The document discusses algorithms and flowcharts. It defines an algorithm as a step-by-step procedure to solve a problem and get a desired output. Common algorithm categories include search, sort, insert, update, and delete operations on data structures. Flowcharts provide a graphical representation of an algorithm's steps and logic. The document presents examples of an algorithm to add two numbers and the benefits of algorithms and flowcharts, such as effective problem analysis, proper documentation, and efficient coding and debugging. It also notes potential disadvantages like complexity when logic is complicated and the need to redraw flowcharts during alterations.

Algorithm - Introduction
This document discusses algorithms including:
- An algorithm is a set of instructions to accomplish a task, with inputs and outputs.
- Characteristics of algorithms include being definite, finite, unambiguous, and efficient.
- The design process involves understanding the problem, capabilities of the device, choosing exact or approximate solutions, selecting a data structure, and techniques like divide-and-conquer.
- Algorithms can be specified through languages, pseudocode, or flowcharts and must be proven correct. Their analysis considers time and space complexity.
Algorithm
A typical programming task can be divided into two phases:
Problem-solving phase: produce an ordered sequence of steps that describe the solution of the problem this sequence of steps is called an algorithm.
Implementation phase: implement the program in some programming language.
Every algorithm must satisfy the following criteria:
Input. Zero or more quantities are externally supplied.
Output. At least one quantity is produced.
Definiteness. Each instruction must be clear and unambiguous(Unique meaning).
Finiteness. An algorithm terminates in a finite number of steps.
Effectiveness. Every instruction must be basic enough to be carried out than, means not so complex.
An algorithm is a finite set of steps defining the solution of a particular problem.
What is the difference between an algorithm and a program?
a program is an implementation of an algorithm to be run on a specific computer and operating system.
an algorithm is more abstract – it does not deal with machine-specific details – think of it as a method to solve a problem.
What is a good algorithm?
Efficient algorithms are good, we generally measure the efficiency of an algorithm based on:
Time: the algorithm should take minimum time to execute.
Space: the algorithm should use less memory.
DIFFERENCE BETWEEN ALGORITHM AND PSEUDOCODE?
An algorithm is a well-defined sequence of steps that provides a solution for a given problem, while pseudocode is one of the methods that can be used to represent an algorithm.
While algorithms can be written in natural language, pseudocode is written in a format that is closely related to high-level programming language structures.
But pseudocode does not use specific programming language syntax and therefore could be understood by programmers who are familiar with different programming languages. Additionally, transforming an algorithm presented in pseudocode to programming code could be much easier than converting an algorithm written in natural language.

A queue is a first-in, first-out (FIFO) data structure where elements are added to the rear of the queue and removed from the front of the queue. Common queue operations include enqueue to add an element, dequeue to remove an element, and functions to access the front and rear of the queue. Queues can be implemented using arrays or linked lists, with pointers or indexes to track the front and rear of the queue. The document provides examples of these operations and overflow/underflow conditions that can occur.
Lect 10 Zaheer Abbas
A linked list is a linear data structure where each element is linked to the next element via a pointer. Each element, called a node, contains data and a pointer to the next node. The first node is referenced by a pointer called the head. Linked lists allow for efficient insertion and removal of nodes throughout the list since nodes are not confined to adjacent memory locations. Linked lists can grow and shrink dynamically as nodes are added or removed.
Lect 15-16 Zaheer Abbas
The document discusses stacks, which are linear data structures that only allow insertion and removal of elements from one end. Stacks follow the LIFO (last in, first out) principle. The basic stack operations are push, which adds an element to the top, and pop, which removes the top element. Stacks can overflow if full and underflow if empty. Stacks can be implemented using arrays, with a pointer tracking the top index. Pseudocode provides algorithms for push and pop operations on a stack implemented using an array.

4. Selection (Binary) - Used to represent operations where there are two possible selections based on a condition being true or false.
5. Repetition - Allows a portion of the algorithm to be repeated as long as a condition is met. It has two variants: pre-test and post-test.
Introduction to algorithms
This document discusses algorithms and their analysis. It defines an algorithm as a set of unambiguous instructions to solve a problem with inputs and outputs. Good algorithms have well-defined steps, inputs, outputs, and terminate in a finite number of steps. Common algorithm analysis methods include calculating time and space complexity using asymptotic notations like Big-O. Pseudocode and flowcharts are commonly used to represent algorithms. Asymptotic analysis determines an algorithm's best, average, and worst case running times.
What is algorithm
The document discusses algorithms and their key characteristics. It defines an algorithm as a set of well-defined steps to solve a problem. Algorithms must be precise, terminate in a finite time, and not repeat infinitely. The document provides examples of algorithm problems and their solutions, and discusses common ways to represent algorithms as programs, flowcharts, or pseudocode. Flowcharts use symbols to visually represent the logic and sequence of operations.

Flip-flops are fundamental building blocks of digital electronics that can store state information. There are several types of flip-flops including D, T, JK, and SR flip-flops. Flip-flops are used as data storage elements, for counting pulses, and synchronizing signals. Counters are digital circuits that store and sometimes display the number of times an event occurs, often in relation to a clock signal. Digital logic design involves the analysis and design of combinational and sequential circuits using techniques like minimization and optimization.
C# by Zaheer Abbas Aghani
C# is an object-oriented programming language created by Microsoft. It was created by a team led by Anders Hejlsberg with the goal of combining the best aspects of existing languages and improving upon them. C# code is compiled into an intermediate language called IL, which is then executed by the Common Language Runtime (CLR). Key concepts of object-oriented programming in C# include classes, objects, abstraction, encapsulation, polymorphism, and inheritance. Classes define the attributes and behaviors of objects, and objects are instances of classes.
C# by Zaheer Abbas Aghani
C# is an object-oriented programming language created by Microsoft that can be used to create a variety of applications. The key steps in executing a C# program are compilation, where source code is converted to bytecode, and execution, where the bytecode is converted to machine code and run. C# supports important object-oriented concepts like classes, objects, inheritance, polymorphism, abstraction and encapsulation. Classes define the attributes and behaviors of objects, and objects are instantiated from classes. Constructors initialize new objects.
Lect 22 Zaheer Abbas
Binary trees can be implemented using two representations: linked and array. The linked representation stores each node as a structure with data, left child, and right child pointers. The array representation stores tree data in a 2D array with a root pointer variable. There are four basic tree operations: traversing, searching, inserting, and deleting. Traversing involves visiting nodes in different orders like preorder, inorder, and postorder.
Lect 21 Zaheer Abbas
The document defines and describes various types of trees, including binary trees. It explains that a tree is a non-linear data structure used to represent hierarchical relationships, with each node having up to two children. The document also defines key tree terms like root, parent and child nodes, leaf nodes, subtrees, and internal nodes. Specific tree types covered include binary trees, strictly binary trees, complete binary trees, extended binary trees, and binary search trees.
Lect 11-12 Zaheer Abbas
The document discusses linked list data structures and common operations performed on linked lists such as traversing, searching, insertion, and deletion. It provides algorithms to perform each operation. For traversing, the algorithm uses a pointer PTR that moves from node to node, printing the info of each node. For searching, the algorithm traverses and compares the info of each node to the search item. Insertion can occur at the beginning or between nodes. Deletion can occur at the beginning, between nodes, or at the end of the list.
Lect 9(pointers) Zaheer Abbas
Pointers provide a way to access and manipulate variables indirectly through memory addresses. A pointer variable stores the address of another variable. Pointers allow dynamic memory allocation and more efficient data manipulation. They are useful for implementing data structures like linked lists and arrays. Pointers can be declared, initialized, and dereferenced using operators like asterisk (*) and ampersand (&). Arithmetic operations on pointers modify the address they point to rather than the underlying value.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
