Solution: Minimum Operations to Make All Array Elements Equal

Explore how to calculate the minimum number of operations to make all elements in an array equal to given query values. This lesson teaches the use of sorting, prefix sums, and binary search to efficiently compute and return operation costs for multiple queries.

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 ==== queries.length

  • 11 \leq n, m 103\leq 10^3

  • 11 \leq ...
