Consider the following array of numbers A = {15, 4, 21, 12, 10, 0, 21, 12, 3, 14}. Show the result of the various passes needed to sort A : Using Insertion sort Using Bubble sort Using Selection sort Using RadixSort (r = 5) Use a binary tree to show the different recursive calls resulting from using MergeSort to sort A
Consider a list L = {387, 690, 234, 435, 567, 123, 441}. Here, the number ofelements n = 7, the number of digits l = 3 and radix r = 10. This means that radixsort would require 10 bins and would complete the sorting in 3 passes. illustrates the passes of radix sort over the list. It is assumed that each key is thrown into the bin face down. At the end of each pass, when the keys are collected from each bin in order, the list of keys in each bin is turned upside down to be appended to the output list
Implement the following two sorting algorithms in a program called p3.py. Write two separate functions for these algorithms. Both functions must take a list of integers as the input parameter.1) Bogosort: first shuffle the list argument (i.e., randomize the positions of every element) and then check to see if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.2) Bozosort: choose two elements in the list at random, swap them, and then check if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.Write a main() function and call both sorting functions using the same list as their arguments. The list can be of any size (try a small list first). Does any of your algorithms terminate? If yes, count the number of iterations it uses to sort the list. Does it always use the same number of repetitions? If…

Q1: Suppose you are given an array A of n Your task is to sort n numbers stored in array A by reading the first element of A and placing it on its original position (position after sorting). Then read the second element of A, and place it on its original position. Continue in this manner for the first n-1 elements of A. What type of sorting is this? Write the algorithm and also mention the name of this sorting algorithm. What loop invariant does this algorithm maintain? Give the best-case and worst-case running times of this sorting algorithm.

A variation of the bubble sort algorithm known as a gap sort examines elements that are some number I positions apart, where I is an integer less than n, rather than neighbouring elements each time through the list. The first element, for instance, would be compared to the element I + 1), the second element, to the element I + 2), the nth element, to the element (n - I and so on. Once all the components that can be compared have been done so, the iteration is finished. I am decreased by a factor greater than 1 on the following iteration, and the procedure continues until I is less than 1. Apply the gap filter.

Let L={x1,x2,…,xn} be a list of n elements. Let us search for a key K in the list L. If the key is presented in the list L at index(or position) j then partition the list L into disjoint lists L1 and L2 such that L1={x[i]:x[i]εL such that i≤j} and L2={x[i]:x[i]εL such that i>j}. If the key is not present in the list output is “no”. Write an algorithm (using single linked list) and subsequent C program for your algorithm to compute lists L1 and L2 for the given list L and key K. Note: Don’t use any inbuilt functions in your program. Example1: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 27 then L1={16, 15,1,27} and L2={19, 100,200, 3}. Example 2: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 127 then no.
