Solution: Split Array Into Two Arrays to Minimize Sum Difference

Explore how to divide an integer array into two equal-sized subarrays such that the absolute difference of their sums is minimized. Learn to apply the meet-in-the-middle strategy combined with binary search for optimal and efficient problem solving, reducing computational complexity substantially.

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: ...
