Find subarray with given sum

Harsh Jain on Instagram: "Maximum Subarray Sum O(N^2) Approach Explained | Data Structures & Algorithms ​Description: ​In this video, we dive into the Maximum Subarray Sum problem. I will show you how to solve this classic coding interview question using an approach with O(N^2) Time Complexity. ​While many are familiar with the O(N^3) brute force method, optimizing it to O(N^2) is a crucial step in understanding how to reduce nested loops and improve algorithm efficiency before moving on to Kada

A subarray is any contiguous block of an array's elements. Given an array of integers, find the sum of all elements of all subarrays of that array in Python. For example, a three-element array [4, 5, 6] would output to 50.
