Minimum Size Subarray Sum

Explore how to apply the sliding window pattern to efficiently solve the minimum size subarray sum problem. Understand how to find the shortest contiguous subarray whose sum meets or exceeds a target value, improving your problem-solving strategies for coding interviews.

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
  • 11 \leq nums.length \leq 10310^3
  • 11 \leq nums[i] \leq 10310^3
