Describe an efecient in-place algorithm called Partition-Even-Odd(A) that partitions an array A in even and odd numbers. The algorithm must terminate with A containing all its even elements preceding all its odd elements. For example, for input A = [7, 17, 74, 21, 7, 9, 26, 10], the result might be A = [74, 10, 26, 17, 7, 21, 9, 7]. Partition-Even-Odd must be an in-place algorithm. What does this mean about your algorithm? (a) Write the pseudo-code for Partition-Even-Odd. (b) Characterize the complexity of Partition-Even-Odd. Brie y justify your answer. (c) Formalize the correctness of the partition problem as stated above, and prove that Partition-Even- Odd is correct using a loop-invariant.

Given an Array A = <5,4,3,2,1> what will be the updated array A after we run some partition (A, 1 , 5) some partition (a, p , r) mid = (p + 2)/2 x = a[mid] i = p - 1 j = r + 1 while (true) do j = j - 1 while (A[j] > x do i = i + 1 while (A[i] < x) if (i < j) swap A[i} and A[j} else return j
Given an unsorted array A of integers of any size, n ≥ 3, and an integer value x, write an algorithm as a pseudo code (not a program!) that would find out if there exist EXACTLY3 occurrences in the array with value x. What is the time complexity of your algorithm, in terms of Big-O? What is the space complexity of your algorithm, in terms of Big-O? What if , the given array A is sorted. Will time complexity change from the case that A was unsorted? • If yes; give a new algorithm that achieves this better complexity (indicate the time complexity as of that algorithm). • If no, explain why such new constraints/conditions cannot lead to a better time complexity.
Let A and B be two arrays of length n, each containing a random permutation of the numbers from 1 to n. An inversion between the two permutations A and B is a pair of values (x, y) where the index of x is less than the index of y in array A, but the index of x is more than the index of y in array B. Design an algorithm which counts the total number of inversions between A and B that runs in O(n log n) time.
Consider a hybrid sorting algorithm that combines Mergesort with Insertion Sort.It uses Mergesort until the number of elements in the input becomes smaller than or equal to 8, after which it switches to Insertion Sort. What is the number of key comparisons performed by this hybrid sorting algorithm in the best case when running on an input array of size n? Briefly justify your answer. You could assume n = 2k, k is more than 3
Consider an array A of N values (N entered by the user). Write a C program that creates a second array B such that the i-th element of B, i.e., B[i] is equal to A[0] *A[1] * A[2] * ... A[i]; In other words:- B[0] = A[0]- B[1] = A[0] * A[1];- B[2] = A[0] * A[1] * A[2];- B[3] = A[0] * A[1] * A[2] * A[3]- ....etc.For this exercise, we would like to implement two solutions and compare their complexity /performance in terms of computation time.Solution 1: Implement blindly the following algorithms: for each element B[i], compute A[0] *A[1] * A[2] * .... *A[i] and save the result in B[i];To test the solution, create an array A of 1000 elements and initialize each of its elements with arandom value (instead of asking the user to . To do that, use the function rand, which, every timecalled, returns a random number Questions:- How long does your program take to produce the solution?- Analyze the solution above and explain why it is taking long time.

A shrinkable word is a word with more than two characters that can be reduced down to a two-character c-string by deleting one character at a time such that, at each stage, the remaining c-string is a word that must be found in a two-dimensional c-string array. For example, to check if the word startling is shirnkable we start by deleting one character; it could be any character in the word. When trying to delete the character 'l', the c-string becomes starting which is a c-string found int the two-dimensional array dictionary. Next, we continue by trying to delete another character which turns out to be the second 't' and the c-string becomes staring. In the same fashion, the c-string becomes string, sting, sing, sin, and finally in which must also be found in the dictionary. At this point, the original word (i.e. startling) is considered shrinkable. An example of non-shrinkable word is table. When trying to delete one character, we get the c-string able. However, when trying to…

Create a programme that generates the best-case array for sort() (with no duplicates). an array of N items with different keys with the characteristic that each partition produces subarrays that differ in size by no more than one (the same subarray sizes as would occur for an array of N equal keys). (Ignore the first shuffle for the sake of this exercise.)
Write a program that reads an array A of N elements containing only 0's and 1's. Your program should find the position of a 0 and replace it with a 1 to get the longest continuous sequence of 1's. Let this position of 0 be called P. Print P if such a 0 exists and print -1 if the original array A contains only 1's. Assume the array indexing starts from 0.
