We are given a 2-D array that will be used to form a matrix pattern. The task is to rotate a matrix by 90 degrees in an anti-clockwise direction such that the first row becomes the first column, second row becomes second column and third becomes third column and the ... Read More

Given a list of words. The goal is to create all possible sentences that can be formed by taking words from the list using a recursive approach. You can only take one word at a time from both the lists.Let us see various input output scenarios for thisInput −sentence[row][col] = {{"I", ... Read More

We are given with an integer and the agenda here is to reverse the digits of the number and add the reversed number to the original number and check if the resultant number is a palindrome or not and the process is repeated until it does. The breaking point of ... Read More

Given an integer n that is not negative. The goal is to reverse the bits of n and report the number that results from doing so. While reversing the bits, the actual binary form of the integer is used; no leading 0s are taken into account.Let us see various input ... Read More
