Solution: Split Array Into Two Arrays to Minimize Sum Difference

Explore how to partition an array into two subarrays of equal length to minimize the absolute sum difference. Understand the application of binary search combined with the meet-in-the-middle strategy to efficiently find the optimal partition without exhaustive search. This lesson helps you implement a solution with reduced time complexity by generating subset sums for array halves and performing targeted binary searches.

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.
