Solution: Split Array Into Two Arrays to Minimize Sum Difference

Explore how to minimize the absolute difference between sums of two equal-sized subarrays by combining binary search with the meet-in-the-middle technique. Understand how splitting an array, generating subset sums, and using binary search efficiently finds the optimal partition while reducing computational complexity.

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.
