Solution: Minimum Size Subarray Sum

Statement

Given an array of positive integers, nums, and a positive integer, target, find the minimum length of a contiguous subarray whose sum is greater than or equal to the target. If no such subarray is found, return 0.

Constraints:

• $1$ $\leq$ target $\leq$ $10^9$
• $1$ $\leq$ nums.length $\leq$ $10^5$
• $1$ $\leq$ nums[i] $\leq$ $10^4$
