<p>Given an array of integers <code>nums</code>, half of the integers in <code>nums</code> are <strong>odd</strong>, and the other half are <strong>even</strong>.</p>
|
|
|
|
<p>Sort the array so that whenever <code>nums[i]</code> is odd, <code>i</code> is <strong>odd</strong>, and whenever <code>nums[i]</code> is even, <code>i</code> is <strong>even</strong>.</p>
|
|
|
|
<p>Return <em>any answer array that satisfies this condition</em>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [4,2,5,7]
|
|
<strong>Output:</strong> [4,5,2,7]
|
|
<strong>Explanation:</strong> [4,7,2,5], [2,5,4,7], [2,7,4,5] would also have been accepted.

|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [2,3]
|
|
<strong>Output:</strong> [2,3]
|
|
</pre>
|
|
|
|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>2 <= nums.length <= 2 * 10<sup>4</sup></code></li>
|
|
<li><code>nums.length</code> is even.</li>
|
|
<li>Half of the integers in <code>nums</code> are even.</li>
|
|
<li><code>0 <= nums[i] <= 1000</code></li>
|
|
</ul>
|
|
|
