Solution: Split Array Into Two Arrays to Minimize Sum Difference

Explore how to minimize the absolute difference between sums of two equal subarrays by applying a modified binary search combined with a meet-in-the-middle approach. Learn to generate subset sums, use binary search effectively, and optimize time and space complexity for efficient problem-solving.

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:

  • 1 \leq nn \leq 15

  • nums.length ...
