                                                          Problem Statement   Harry and Potter choose a word string. Harry chose a number M  (less than the length of the string) and Potter chose N (less than the length of the string).  Harry will cut M letters from the end of the string, add them to the beginning and will give it to Potter. Then, Potter will also cut N letters from the end of the string,  add it to the beginning and give it to Harry. This process will continue till they get the original word string back.  For a given string and given values of M and N, find the number of turns in which they will get the original word string back . Example If the string is AbcDef, M= 1 and N = 2 the Output must be 4 4604  Explanation This is how the words tend will change.

                                                              Perfect Square                                                         Problem Statement You're given an array A of size N, the task is to remove all the elements from the array except perfect squares of any integer and print the updated ay For example, if the given array is 9 12 16. Here, 9 and 16 are the perfect square of numbers 3 and 4 respectively. After removing others from the the t  Input Format: The input consists of two lines:  The first line contains an integer N denoting the size of an array A. The second line contains N integers separated by space denoting elements of the array A. The input will be read from the STDIN by the candidate Output Format:  Print the updated array with each element separated by space, if the updated array is empty then print -1. The output will benatched to the candidate's output printed on the STDOUT Constraints:   1< N < 500   • 1< A; S 50000 Example: Input: 100

EV_First Unique Character A unique character is one that appears only once in a string. Given a string consisting of lowercase English letters only, return the index of the first occurrence of a unique character in the string using 1-based indexing. If the string does not contain any unique character, return-1. Example s="statistics" The unique characters are [a, c] among which a occurs first. Using 1-based indexing, it is at index 3. Function Description Complete the function getUnique Character in the editor below. getUniqueCharacter has the following parameter(s): string s: a string Returns int: either the 1-based index or -1 Constraints • 1 s. length of ss 105 . The string s consists of lower

                                                             EV_Minimize Array Cost connect with me on Facebook Twitter Instagram Github Youtube len(arr)-1 Σ(arri-arri-1)² i=1 len(arr) is the size of the array. Insert any integer at any location of the array such that the cost of the array is minimized. Find the minimum possible cost of the array after inserting exactly one element. Example a= [1, 3, 5, 2, 10] The cost of the array before insertion =(1-37+(3-57+(5-2)²+(2-102²= 81. Two of many scenarios are shown below. 1. Insert 4 between 3 and 5, cost of array = (1-37+(3-47+(4-57+(5-2)²+(2 107²2² = 79. 2. Insert 6 between 2 and 10, cost of array =(1-37+(3-5)+(5-27²+(2-67² + (6 107² = 49. It can be proven that 49 is the minimum cost possible. Return 49.
