Solution: Minimum Size Subarray Sum

Explore the sliding window technique to solve the minimum size subarray sum problem. This lesson guides you through implementing a linear time algorithm that finds the smallest contiguous subarray with a sum greater than or equal to the target. Understand how to efficiently manage window boundaries and track sums to optimize your solution. By the end, you will be able to apply this approach to similar coding challenges and assess time and space trade-offs.

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 10410^4
