Solution: Sum of Mutated Array Closest to Target

Explore how to solve the sum of mutated array closest to target problem by sorting the array and carefully selecting replacement values to minimize the difference from the target. Learn to iterate, calculate replacements, and handle ties effectively to find the optimal solution with O(n log n) time complexity.

Statement

Given an integer array arr and a target value target, find an integer value such that if all the numbers in arr greater than value are replaced with a value, the sum of the array gets as close as possible to the target.

Choose the smaller value if there’s a tie (two value options are equally close to the targe).

Note: The answer doesn’t have to be a number from the array.

Constraints:

  • 11 \leqarr.length 103 \leq 10^3 ...
