<p>给定一个含有 <code>n</code><strong> </strong>个正整数的数组和一个正整数 <code>target</code><strong> 。</strong></p>
|
||
|
||
<p>找出该数组中满足其和<strong> </strong><code>≥ target</code><strong> </strong>的长度最小的 <strong>连续子数组</strong> <code>[nums<sub>l</sub>, nums<sub>l+1</sub>, ..., nums<sub>r-1</sub>, nums<sub>r</sub>]</code> ，并返回其长度<strong>。</strong>如果不存在符合条件的子数组，返回 <code>0</code> 。</p>
|
||
|
||
<p> </p>
|
||
|
||
<p><strong>示例 1：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>target = 7, nums = [2,3,1,2,4,3]
|
||
<strong>输出：</strong>2
|
||
<strong>解释：</strong>子数组 <code>[4,3]</code> 是该条件下的长度最小的子数组。
|
||
</pre>
|
||
|
||
<p><strong>示例 2：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>target = 4, nums = [1,4,4]
|
||
<strong>输出：</strong>1
|
||
</pre>
|
||
|
||
<p><strong>示例 3：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>target = 11, nums = [1,1,1,1,1,1,1,1]
|
||
<strong>输出：</strong>0
|
||
</pre>
|
||
|
||
<p> </p>
|
||
|
||
<p><strong>提示：</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>
|
