    Merge Sort Problem Statement

    Example:

    Input:
    ARR = [5, 3, 8,...
  • Ans. Recursion

    The basic idea is that we divide the given ‘ARR’ into two-part call them ‘leftHalves’ and ‘rightHalves’ and call the same function again with both the parts. In the end, we will get sorted ‘leftHaves’ and sorted ‘righthalves’ which we merge both of them and return a merged sorted ‘ARR’.

    We implement this approach with a divide and conquer strategy.
