Solution: Split Array Into Two Arrays to Minimize Sum Difference

Explore how to efficiently split an array into two equal subarrays to minimize the absolute difference between their sums. Understand the use of binary search combined with meet-in-the-middle, generating and pairing subset sums to solve this partition problem with optimized time and space 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.

Constraints: ...
