    209 - Minimum Size Subarray Sum.

    Medium

    Given an array of positive integers nums and a positive integer target, return the minimal length of a contiguous subarray [numsl, numsl+1, …, numsr-1, numsr] of which the sum is greater than or equal to target. If there is no such subarray, return 0 instead.

    Example 1:

    Input: target = 7, nums = [2,3,1,2,4,3]

    Output: 2

    Explanation: The subarray [4,3] has the minimal length under the problem constraint.

    Example 2:

    Input: target = 4, nums = [1,4,4]

    Output: 1

    Example 3:

    Input: target = 11, nums = [1,1,1,1,1,1,1,1]

    Output: 0

    Constraints:

    • 1 <= target <= 109
    • 1 <= nums.length <= 105
    • 1 <= nums[i] <= 105

    Follow up: If you have figured out the O(n) solution, try coding another solution of which the time complexity is O(n log(n)).
