Solution: Sum of Mutated Array Closest to Target

Discover how to solve the sum of mutated array problem by sorting the array and applying binary search to find a replacement value that minimizes the difference to the target. Understand the approach of updating the remaining target and computing the best candidate efficiently.

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 ...
