Solution: Split Array Into Two Arrays to Minimize Sum Difference

Understand how to efficiently split a 2n-length array into two subarrays of size n to minimize the absolute difference between their sums. This lesson teaches the meet-in-the-middle approach combined with binary search to optimize subset sum computations and avoid exponential computations, helping you solve partition problems with reduced time 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.
