- In the C(89) standard of C programming language Suppose you are given an array of integers. You want to insert a number x to the array and rearrange so that all the elements are less than or equal to x are before x, and the elements after x are greater than x. For example, suppose the list is {3, 2, 7, 0 1, 5} and x is 4, since 3, 2, 0, and 1, are less than or equal to 4, 7and 5 are greater than 4, the new array is {3, 2, 0, 1, 4, 7, 5}. The new array has the length of n+1 where n is the length of the input array. Example input/output #1: Enter the length of the array: 10 Enter the elements of the array: 3 5 14 03 92 8 11 Enter the number for insertion: 3 Output: 3 1 0 3 2 3 5 4 9 8 11 Example input/output #2: Enter the length of the array: 8 Enter the elements of the array: 5 0 1 3 4 1 7 3 5 Enter the number for insertion: 6 Output: 5 0 4 1 3 5 6 13 7 1) Name your program arrays.c 2) Include the rearrange( ) function to rearrange the array: void rearrange(int *a, int n, int…In C++, write a program that reads in an array of type int. You may assume that there are fewer than 20 entries in the array. The output must be a two-column list. The first column is a list of the distinct array elements and the second column is the count of the number of occurences of each element.Write a recursive function that finds the minimum value in an ArrayList. Your function signature should be public static int findMinimum(ArrayList<Integer>) One way to think of finding a minimum recursively is to think “the minimum number is either the last element in the ArrayList, or the minimum value in the rest of the ArrayList”. For example, if you have the ArrayList [1, 3, 2, 567, 23, 45, 9], the minimum value in this ArrayList is either 9 or the minimum value in [1, 3, 2, 567, 23, 45] Hint:The trick is to remove the last element each time to make the ArrayList a little shorter. import java.util.*; public class RecursiveMin{public static void main(String[] args){Scanner input = new Scanner(System.in);ArrayList<Integer> numbers = new ArrayList<Integer>();while (true){System.out.println("Please enter numbers. Enter -1 to quit: ");int number = input.nextInt();if (number == -1){break;}else {numbers.add(number);}} int minimum =…

If the list contains no even integers, the function will return None. For Example : min_odd([45, 62, 19, 22, 26, 18, 3, 5, 14])Expected answer is 14 min_odd([])Expected answer is None Write a function index_of that takes as an argument an integer (supposedly even) and a list, and returns the index to which this integer appears in the list. If the integer does not appear, the function will return None. It is assumed here for simplicity that the integer searched for does not appear several times in the list. Hint: if the for e in list loop doesn't suit you, remember that you can make a for + range or a while. .. For Example: index_of(34, [3, 67, 62, 34, 19, 24])Expected answer is 3 index_of(16, [2, 6, 104, 5, 25, 18, 50, 16])Expected answer is 7Q 5. Write a program in C++ using object oriented concepts to input a list of numbers in an array and then rearrange this array in such a way that all the odd numbers appear in the beginning of the array and all the even numbers appear in the end of the array. E.g., if the input list is 1,4,2,7,6,5,9, then after rearrangement the list should be: 1,5,7,9,2,4,6. [3]
- Assume that L is a list of Boolean values, True and False. Write a program in python with a function longestFalse(L) which returns a tuple (start, end) representing the start and end indices of the longest run of False values in L. If there is a tie, then return the first such run. For example, if L is False False True False False False False True True False False 0 1 2 3 4 5 6 7 8 9 10 then the function would return (3, 6), since the longest run of False is from 3 to 6.All the problems are to be coded in Python/Java. You must explicitly solve each problem below using your own logic. For example, Do not use existing library functions, such as sum( ), which computes the sum of a list. Instead, you must use for/while loop to sum up the items in a list. a. Write code for a CharList class which converts a string to a linked list of characters in the string. * b. Add a class member function which outputs if the linked list in Problem a. is a palindrome. What is the Big-O upper bound? c. What change could be made to the class definition in Problem a. to make your solution in Problem b. more efficient? Explain. What is the Big-O upper bound? Hint: Think of how the palindrome determination problem is solved for a regular string. d. Add a method to the classic List class we discussed in class that reverses the list. That is, if the original list is A -> B ->C, all of the list's links should change so that C-> B-> A. Make your solution as efficient as possible.…Please Program this in SMALLTALK Extend class Array with the method contains:. It returns true if the argument is in the array, and false if not.

- Write code in C++, C# or Python to solve the following problem: In a party there are N persons and we have M raffles. One person may participate in any number of raffles (from 0 to M). At the end of the day, host of the party comes to you and gives you M lists. Each list contains multiple integer numbers which are the "raffle ID numbers" of the participants. Then, for each list an integer number, I, is announced to determine the winner of the raffle: the winner is the person with raffle ID number K such that K is larger than exactly I numbers in that list. To help the host to find the winners you want to write a program. Input Format First line of the input is N and M. Then, there are M lines, each one contains integer numbers between 1 and N. Each list may contain at most N numbers. At the end of each line there is -1. After these lines there is one line which contains M integers to announce the winners. If the j-th number in this line is I it means that the winner of list j…In the C programming language Suppose you are given an array of integers. You want to insert a number x to the array and rearrange so that all the elements are less than or equal to x are before x, and the elements after x are greater than x. For example, suppose the list is {3, 2, 7, 0 1, 5}and x is 4, since3, 2, 0, and 1,are less than or equal to 4,7and 5 are greater than 4, the new array is {3, 2, 0, 1, 4, 7, 5}.The new array has the length of n+1 where n is the length of the input array. Example input/output #1: Enter the length of the array: 10 Enter the elements of the array: 3 5 14 03 92 8 11 Enter the number for insertion: 3 Output: 3 1 0 3 2 3 5 4 9 8 11 Example input/output #2: Enter the length of the array: 8 Enter the elements of the array: 5013 4 1 7 3 5 Enter the number for insertion: 6 Output: 5 0 4 1 356 13 7 1) Name your program arrays.c 2) Include the rearrange( ) function to rearrange the array: void rearrange(int *a, int n, int insert, int *b); a…QUESTION: NOTE: This assignment is needed to be done in OOP(c++/java), the assignment is a part of course named data structures and algorithm. A singly linked circular list is a linked list where the last node in the list points to the first node in the list. A circular list does not contain NULL pointers. A good example of an application where circular linked list should be used is a items in the shopping cart In online shopping cart, the system must maintain a list of items and must calculate total bill by adding amount of all the items in the cart, Implement the above scenario using Circular Link List. Do Following: First create a class Item having id, name, price and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in cart and next pointer Implement the method to add items in the array, remove an item and display all items.
