<p>给定两个大小分别为 <code>m</code> 和 <code>n</code> 的正序（从小到大）数组 <code>nums1</code> 和 <code>nums2</code>。请你找出并返回这两个正序数组的 <strong>中位数</strong> 。</p>
|
|||
|
|
|
|||
|
|
<p>算法的时间复杂度应该为 <code>O(log (m+n))</code> 。</p>

<p><strong>示例 1：</strong></p>
|
|||
|
|
|
|||
|
|
<pre>
|
|||
|
|
<strong>输入：</strong>nums1 = [1,3], nums2 = [2]
|
|||
|
|
<strong>输出：</strong>2.00000
|
|||
|
|
<strong>解释：</strong>合并数组 = [1,2,3] ，中位数 2
|
|||
|
|
</pre>

|
<p><strong>示例 2：</strong></p>
|
|||
|
|
|
|||
|
|
<pre>
|
|||
|
|
<strong>输入：</strong>nums1 = [1,2], nums2 = [3,4]
|
|||
|
|
<strong>输出：</strong>2.50000
|
|||
|
|
<strong>解释：</strong>合并数组 = [1,2,3,4] ，中位数 (2 + 3) / 2 = 2.5
