DIY: Find Two Non-Overlapping Subarrays Each with Target Sum

Explore how to identify two non-overlapping subarrays within an integer array that each sum to a target value. Learn to implement a function that returns the minimum combined length of such subarrays or -1 if none exist. This lesson helps develop problem-solving skills for interview challenges requiring efficient subarray sum computations.

Problem statement

In this challenge, you are given an array of integers named arr and an integer named target. Your task is to find two non-overlapping subarrays in arr such that both subarrays ...
