Minimum Size Subarray Sum (Smallest Subarray with Sum Greater than or Equal to the Given Value)

Given an array of positive integers and a positive number k. Find the smallest contiguous subarray whose sum is either greater than or equal to k. If no subarray is found then return 0. In this tutorial, I have explained multiple approaches to find minimum length subarray sum. Java Code - https://webrewrite.com/minimum-size-subarray-sum/ For example - Example 1 - Input : {7, 2, 1, 1, 6, 5}, k = 11 Output: 2 ( subarray {6, 5} has the minimum length ) Example 2 - Input : {1, 4, 3}, k = 12 Output: 0 (No subarray is possible)
