Solution: Minimum Operations to Make All Array Elements Equal

Explore how to efficiently calculate the minimum number of operations to make all elements of an array equal to each query value. Understand the use of sorting, binary search, and prefix sums to split the array and compute costs for increments and decrements. This lesson helps you solve range adjustment problems with optimal time complexity.

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 ==== ...
