Solution: Minimum Operations to Make All Array Elements Equal
Discover how to compute the minimum number of operations needed to make all elements in an array equal to various query values. This lesson guides you through sorting the array, using prefix sums for quick range calculations, and applying binary search to optimize the solution. Understand the time and space complexity to implement efficient algorithms for similar array transformation problems.
We'll cover the following...
Statement
You are given an array, nums, consisting of positive integers of size n and another array queries of size m. For each query 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
numsby 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.
