Bubble Sort: Bubble sort is a simple sorting algorithm that repeatedly swaps adjacent elements if they are in the wrong order. It continues this process until the entire array is sorted. Bubble sort has a time complexity of O(n^2) and is not efficient for large input sizes, but it is ...

Swapping of adjacent bits in C++: Here, we are going to learn how to swap adjacent bits of a number?Submitted by Saksham Bhayana, on December 12, 2018 Problem statement: C++ program to swap all odd bits with even bits (swap adjacent bits). Every even positiC++ program to swap all ...
Input: arr = [3,5,1] Output: true Explanation: We can reorder the elements as [1,3,5] or [5,3,1] with differences 2 and -2 respectively, between each consecutive elements. Example 2: Input: arr = [1,2,4] Output: false Explanation: There is no way to reorder the elements to...
