HackerEarth Operations on an Array problem solution YASH PAL, 31 July 2024 In this HackerEarth Operations on an Array problem solution, You have given an array A containing N elements. You need to make the elements of the array equal. You are allowed to do the following operations: Decrease an element by 1. If the element becomes 0, it is removed from the array. Increase an element by 1. You need to find the minimum number of operations required to do so.
