Understanding the Find Two Non-overlapping Sub-arrays Each With Target Sum Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an array of integers arr and an integer target. You have to find two non-overlapping sub-arrays of arr each with a sum equal target. There can be multiple answers so you have to find an answer where the sum of the lengths of the two sub-arrays is minimum. Return the minimum sum of the lengths of the two required sub-arrays, or return -1 if you cannot find such two sub-arrays.

How Interview Coder Helps
Get real-time assistance for Find Two Non-overlapping Sub-arrays Each With Target Sum problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
arr = [3,2,2,4,3], target = 32Only two sub-arrays have sum = 3 ([3] and [3]). The sum of their lengths is 2.
arr = [7,3,4,7], target = 72Although we have three non-overlapping sub-arrays of sum = 7 ([7], [3,4] and [7]), but we will choose the first and third sub-arrays as the sum of their lengths is 2.
arr = [4,3,2,6,2,3,4], target = 6-1We have only one sub-array of sum = 6.
Constraints
1 <= arr.length <= 1051 <= arr[i] <= 10001 <= target <= 108How Interview Coder Helps with Leetcode Problems
