Solution: Split Array Into Two Arrays to Minimize Sum Difference

Discover how to split an integer array into two equal-sized subarrays to minimize the absolute difference of their sums. Learn to apply the meet-in-the-middle approach combined with binary search for efficient subset sum calculations and optimized solution performance.

Statement

You are given an integer array, nums, consisting of 2n2 * n elements.

Your task is to divide the array into two subarrays of length nn, such that each element in nums belongs to exactly one of the two subarrays, and the absolute difference between their sum is minimized.

Return the minimum possible absolute difference between the sum of the two subarrays.

Constraints: ...
