<p>Given an array of positive integers <code>nums</code> and a positive integer <code>target</code>, return the minimal length of a <strong>contiguous subarray</strong> <code>[nums<sub>l</sub>, nums<sub>l+1</sub>, ..., nums<sub>r-1</sub>, nums<sub>r</sub>]</code> of which the sum is greater than or equal to <code>target</code>. If there is no such subarray, return <code>0</code> instead.</p>

|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> target = 7, nums = [2,3,1,2,4,3]
|
|
<strong>Output:</strong> 2
|
|
<strong>Explanation:</strong> The subarray [4,3] has the minimal length under the problem constraint.

<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> target = 4, nums = [1,4,4]
|
|
<strong>Output:</strong> 1

<p><strong>Example 3:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> target = 11, nums = [1,1,1,1,1,1,1,1]
|
|
<strong>Output:</strong> 0

<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= target <= 10<sup>9</sup></code></li>
|
|
<li><code>1 <= nums.length <= 10<sup>5</sup></code></li>
|
|
<li><code>1 <= nums[i] <= 10<sup>5</sup></code></li>
|
|
</ul>
