Solution: Minimum Operations to Make All Array Elements Equal

Explore how to efficiently calculate the minimum number of increments or decrements needed to make all elements in an array equal to various query values. Learn to apply sorting, prefix sums, and binary search to solve each query by splitting the array and computing cost operations on each side. This lesson helps you understand an optimal approach to tackle range transformation problems using algorithmic techniques.

Statement

You are given an array, nums, consisting of positive integers of size n and another array queries of size m. For each query ii in queries, the goal is to make all elements of nums equal to queries[i]. To achieve this, you can perform the following operation any number of times:

  • Increase or decrease an element of nums by 1.

Return an array answer of size m, where answer[i] is the minimum number of operations needed to make all elements of nums equal to queries[i]. After processing each query, the nums array is reset to its original state.

Constraints

  • n ==== nums.length

  • m ==== ...
