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

Understand how to identify two non-overlapping subarrays within an array where each sums to a given target. This lesson guides you to implement an efficient solution that returns the minimal total length or -1 if no such subarrays exist, helping you tackle real-world coding interview challenges.

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 ...
