in python Purpose The purpose of this assignment is to give you practice with writing loops and introduce you to lists. Problem Write a program that receives a series of numbers from the user and allows the user to press the Enter key to indicate that inputs are done. As each number is input, it is stored into a list. After the user presses the Enter key (i.e., they enter nothing as input), the program should do the following: - If the list has no elements, just prints "Empty List". - If the list has at least one element, you must print: The total number of items in the list The list itself sorted in ascending order. The sum of all the elements in the lis. The average of the elements in the list. The largest value in the list. The smallest value in the list. The first half of the list. (If the list has an odd number of elements, you can exclude the middle element. For example, if there are 5 elements, just print the first 2 .) Each individual list element. You must use a loop to iterate through the list to print each element, and each element must be separated by a tab character (t). Inputs Any input other than a number or the Enter key should be caught using an exception with an appropriate error message and the program should continue seeking input. Comments Make sure your code is sufficiently commented! In this casse, you'll want to include your name and denote where input is collected, where errors are handled, and where the various list calculations occur. Hint for stopping input An easy way to capture whether the Enter key was pressed or not is to initially accept the input as a string. and then convert it to integer, all within a Try block: try: input string = input("Enter a Number.") number = int(input string) If it causes an exception, in your except clause you can check for cither the value of the input_string variable to be an empty string (which is two double quotes without anything in it) or the length of the string being zero (the function len can be used). If it's not an empty string but invalid input (like nonnumeric input) you must continue to seck input after a proper error message. .

Answer should be in MIPS please! Please ensure you are following the directions. Thank you in advanced! Your program should be able to take one integer values from user input until you enter 0 and program should end if user types in an integer 0. (The prompt should be Enter an integer: ) - Store the integer into $t5 and multiply the number by 8 using shift operations (Do not use multiplication). And then print the values of bit number 6 to 10 of $t5. (The rightmost bit is bit 0) - You need give detail comments to explain what is happening in the code. The level of detail will be graded. - You need to show the result screens for at least five pairs of numbers including negative numbers. - You need to use the newlines spaces properly so that the output prints in orderly manner. Your output should look like: The number you entered: After it is multiplied by 8: The bits [6-10] are: (there should be one space between each bit value) Please Note: The program first receives user input (integer) and stores it in $t0. Print the entered number (decimal value) Multiply the number in $t0 and print the number (decimal value) Print the value of Bit #6, 7, 8, 9, and 10 of $t5. (The output should look like: 0 1 1 0 0 ).

Instructions Write a program whose main function is merely a collection of variable declarations and function calls. This program reads a text and outputs the letters, together with their counts, as explained below in the function printResult. (There can be no global variables! All information must be passed in and out of the functions. Use a structure to store the information.) Your program must consist of at least the following functions: Function openFile: Opens the input and output files. You must pass the file streams as parameters (by reference, of course). If the file does not exist, the program should print an appropriate message ("The input file does not exist.") and exit. The program must ask the user for the names of the input and output files. Function count: Counts every occurrence of capital letters A-Z and small letters a-z in the text file opened in the function openFile. This information must go into an array of structures. The array must be passed as a parameter, and the file identifier must also be passed as a parameter. Function printResult: Prints the number of capital letters and small letters, as well as the percentage of capital letters for every letter A-Z and the percentage of small letters for every letter a-z. The percentages should look like this: "25%".This information must come from an array of structures, and this array must be passed as a parameter. Your program should prompt the user for name of the input file, then the name of the output file..

I am stuck on parts E and F Exercise 1: NumberListTester.java Class NumberList implements a simple list of Integers, using an ArrayList. NumberListTester generates 10 random, positive, 2-digit ints, and adds them to the list. It then calls method printList which prints the items on the list. Run the program until you understand what it does. a. Write the body of the method printReversed, which prints the list items in reverse order. Add a statement in main to call printReversed after the call to printList. Check ______ b. Write the body of the method printEveryOther, which prints every other item on the list, beginning with the first one. In main, replace the statement that calls printReversed with one that calls printEveryOther. Check ______ c. Write the body of the method printEvens, which prints all the even-numbered ints on the list. In main, replace the statement that calls printEveryOther with one that calls printEvens. Check ______ All this printing is getting a bit tedious. Let\'s try some more fun operations. d. 0. Add a new ArrayList-of-integer instance variable called bigList to the NumberList class Add a statement to the NumberList constructor that creates an empty ArrayList object pointed to by bigList Delete the call to printEvens from main. Write the body of the method splitList, which copies all ints that are greater than or equal to 50 from aList to bigList. Add a method to the NumberList class to print bigList. Add a sequence of method calls in main to verify that the splitList method is working correctly. I.e., after calling splitList, call again the method that prints the original list and then call the method you wrote in step 4 to print the bigList. Check _____ E. Add a method insert to the NumberList class that takes two parameters of type int. The first parameter is the index at which to insert a new number into the list, and the second is the number to be inserted. E.g., if the first param is 4 and the second is 37, then 37 will be inserted at index 4 in aList (i.e., as the new 5th list element). The number inserted does not replace the number currently at that position, but is inserted just before it. Hint: The ArrayList class has a method that does exactly this. Call that method from your insert method. Now add statements to main to allow the user to specify the number to insert and the position at which to insert it. Then, after inserting the new number, print the updated list. Check _____ F. Finally, add code to your insert method that will assure that an IndexOutOfBoundsException cannot be thrown. I.e., your insert method should just print an appropriate error message if the first parameter --- the index at which to insert the new Integer --- is illegal. Hint: What are the legal indices for an ArrayList? What is the smallest? What is the largest? What about the special case of inserting a new value at the end of the list? Try it! Check _____ MY CODE SO FAR: import java.util.ArrayList ; import java.util.Random ; /.

Please help. C++ The program is an interactive program that reads input from the keyboard. Several instructions (listed below) may be entered by the user. For each input, the program will give a short response printed to cout. Each response to cout is followed by a single endl. Important: The program must not try to store all the numbers in a single big array. In fact, it is outlawed by the CSI police that you have any array that is larger than 100 elements. Instead, you should create a frequency array which has indexes from [0] to [99]. A location, such as frequency[i], tells you how many times the number i has occurred in the input. This frequency array should be initialized to all zeros, and each time a number is read, the program will add one to the corresponding array location. For example, frequency[42] begins at zero. When one 42 is read, frequency[42] is increased to one. If another 42 is read, frequency[42] is increased to two, and so on. All of the statistics that you need to calculate can be computed based on the frequency array (so that you don\'t need to store all those numbers separately). • Input: The letter N followed by an integer in the range 0 to 99. The biggest possible input number is 99. The specification does not care what the program does for numbers that are outside of the legal range. Output: The word \"OK\". • Input: The letter S. Output: The output is the SUM of all the input numbers read so far. This output is 0 if there has not yet been any numbers read by the program. • Input: The letter A. Output: The output is the AVERAGE of all the input numbers read so far, calculated as a double number. For example, if there have been four input numbers 2, 2, 6 and 5, then the average is 3.75. If there has not yet been any input numbers, then the program should print the word \"ERROR\" instead of an average. • Input: The letter B. Output: The output is the BIGGEST of all the input numbers read so far, For example, if there have been four input numbers 2, 2, 6 and 5, then the biggest is 6. If there has not yet been any input numbers, then the program should print the word \"ERROR\" instead of a number. • Input: The letter F. Output: The output is the most FREQUENT of all the input numbers read so far--in other words, the number that has been read most often (also called the \"mode\"). If there are several numbers that are equally often, then the smallest number is printed. For example, if there have been four input numbers 2, 2, 6 and 5, then the most frequent is 2. If there has not yet been any input numbers, then the program should print the word \"ERROR\" instead. • Input: The letter H. Output: The output is a count of HOW MANY numbers have been input so far. This could be as small as zero. • Input: The letter M. Output: The output is the MEDIAN of all the input numbers read so far. The median is a number that has no more than half of the input numbers below it and no more than half the input numbers above it. For example.

Solve the following questions by using that elass. 1. The definition of insertFirst(T item) function is missing. Complete it. 2. The definition of insertLast(T item) function is missing. Complete it. 3. The definition of insertAt(T item, int order) function is missing. Complete it. 4. Update print() function to print the list in forward direction. 5. The definition of deleteItem(T item) function is missing. Complete it. 6. Add an extractMax(T max) function to the doublyLinkedList class. The function must extract all nodes containing elements less than max from the list, and construct a new list using those nodes. After the function call, the original list must only have the nodes whose data fields are greater than max, while the new list is containing the smaller ones. The new list must be returned by the function. You're not allowed to delete and/or create new nodes. Your function must just move the subjected nodes from one list to the other. Let the following list be the original list: If the function is called as newList = myList.extractMax (30), then the newList becomes: 2 Assignment Implement a class to represent a circular linked list. You can directly adapt SinglyLinkedList class that we've already defined in linkedList.h. Only the following member functions will be defined for the class: - default constructor to set the pointer data members to NULL and count to 0 . - insertItem to insert a given item to the list. - deleteItem to remove a specific item from the list. Item may occur multiple times, thus the function must remove every occurrences of the item from the list. 1 - print to print the linked list from head to tail. .

Given is the IntNode class that represents an element in a linked list, and the IntList class that represents a linked list (at the end of the question). Add a method signed to the IntList class: public void createList(int[] a, int num) The method will receive as a parameter an array of numbers and the number num, and will create a list from its members so that all the members in the array that are smaller than or equal to num will be at the beginning of the list, and all the members that are greater than num will be at the end of the list. For example, if the array was {4, 2, 7, 5, 3, 8, 1} and num = 3 the list that would be created would be: head 2 3 1 4 7 5 8 null In this case, the numbers 1, 2, 3 are less than or equal to 3 and therefore appear at the beginning of the list, and the other numbers appear later. The internal order of the numbers in each part is not important. Defining the departments for the question: public class IntNode { private int num; private IntNode next; public IntNode(int num, IntNode next) { this.num = num; this.next = next; } public int getNum() { return num; } public void setNum(int num) { this.num = num; } public IntNode getNext() { return next; } public void setNext(IntNode next) { this.next = next; } } public class IntList { private IntNode head; public IntList() { head = null; } } .

Please Please Please Read the instructions and do everything listed there. if you no going to read the instructions and I received bad Credit I will do Bad Rating. Lab #11: Write a program that will do the following: In main, declare an array of size 20 and name it "randomArray." Use the function in step 2 to fill the array. Use the function in step 3 to print the array. Create a function that generates 20 random integers with a range of 1 to 10 and places them into an array. Re-cycle the functions from Lab 10 where appropriate. Make this a function. There will be two arguments in the parameter list of this function: an array and the size of the array. Within the function and the function prototype name the array: intArray. Within the function and the function prototype name the size of the array: size. The data type of the function will be void since the array will be sent back through the parameter list. Bring in the function that generates and returns a random number that you created from the previous module . Call that function from this within the loop that adds random numbers to the array. Display the contents of the array. Re-cycle the function that prints out the contents of an integer array from Lab 10. Make this a function. There will be two arguments in the parameter list of this function: an array and the size of the array. Within the function and the function prototype name the array: intArray. Within the function and the function prototype name the size of the array: size. The data type of the function will be void since the array will be sent back through the parameter list. From main, generate one more random number (also from 1 to 10) from the random number function. Do not put this in an array. This is a stand alone variable that contains one random number. Search though the array and count how many times the extra random number occurs. It is possible that the extra random number may occur more than once or not at all. Output: • Display the entire array. • Display the extra random number. • Depending upon the result of your search, display one of the following: – How many times the random number occurs. – That the random number did not occur at all. Also include: Use a sentinel driven outer While Loop to repeat the task Ask the User if they wish to generate a new set of random numbers Clear the previous list of numbers from the output screen before displaying the new set. NOTE 1: Other than the prompt to repeat the task, there is no input from the User in this program. NOTE 2: This program will have 3 functions: The function that fills the array with random numbers. The function that generates one random number at a time (re-use the one from Lab 10). The function that prints out an array of integers (re-use the one from Lab 10). ======================= Please Read ====================== Searching Through Arrays Now t.

Prompt Your task is to create a connected list implementation and a contiguous list implementation. Both these classes behaves like a list to users but behind the scenes the connected list class uses a Node class to store the data. This Node class simply holds the data as well as a reference to the next Node in the list. The contiguous list class uses an array to hold the data. Both implementations must implement the ListInterface interface. For contiguous list a few things should be considered The array should start at size 10 When an element is added to the list over the size cap the array must be reallocated with double the size. Then all the data must be copied over from the previous array. then you must add the new element. For simplicity the array will only hold Strings. This means the class implements ListInterface specifically for Strings. I have given you this code in the starter file. The ListInterface has the following functions: void prepend(T e) Adds the given element to front of the list void append(T e) Adds the given element to the end of the list void insert(int index, T e) Inserts the given element add the given index Shifts all elements after the given index up by 1 index void empty() Removes all elements from the list boolean has(T e) Returns true if the given element exists in the list, false otherwise T retrieve(int index) Retrieves the element at the given index, if the index doesnt exist then return null boolean isEmpty() Returns true if the list is empty, false otherwise T delete(int index) Deletes the element at the given index and returns it, if the index doesnt exist then return null boolean delete(T e) Deletes the first occurrence of an element from the list if it exists, if an element is removed return true, false otherwise boolean deleteAll(Collection c) Deletes all elements within the given collection, this includes dupli- cates. If it removes an element then return true, otherwise false 1 T mutate(int index, T e) Sets the element at the given index to the given element and returns the old element, return null if the index doesnt exist int length() Returns the current length of the list The following functions must also be implemented: String toString() Override toString from Object Should print out with a square bracket at the front and the back of the list Each element should be seperated by a comma and a space For example if your list had the elements 1 2 and 3 then the output would be [1, 2, 3] boolean equals(Object o) Override equals from Object Should return true if the contents of your list are equal to the contents of os list, otherwise false AND THIS IS THE TEST CLASS.
