Solution: Split Array Into Two Arrays to Minimize Sum Difference

Explore how to minimize the absolute sum difference between two equal-sized subarrays by applying modified binary search combined with the meet-in-the-middle approach. This lesson teaches you to efficiently generate subset sums and use binary search to find optimal partitions, improving problem-solving strategies for coding interviews.

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.
