Solution: Minimum Size Subarray Sum

Understand how to implement the sliding window approach to find the minimum length subarray whose sum meets or exceeds a target value. This lesson helps you practice efficient array traversal for O(n) time complexity and constant space usage.

We'll cover the following...

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:

  • 11 ≤\leq target ≤\leq 10910^9
