Neither Minimum nor Maximum
<p>Given an integer array <code>nums</code> containing <strong>distinct</strong> <strong>positive</strong> integers, find and return <strong>any</strong> number from the array that is neither the <strong>minimum</strong> nor the <strong>maximum</strong> value in the array, or <strong><code>-1</code></strong> if there is no such number.</p>

<p>Return <em>the selected integer.</em></p>

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>

<pre>
<strong>Input:</strong> nums = [3,2,1,4]
<strong>Output:</strong> 2
<strong>Explanation:</strong> In this example, the minimum value is 1 and the maximum value is 4. Therefore, either 2 or 3 can be valid answers.
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> nums = [1,2]
<strong>Output:</strong> -1
<strong>Explanation:</strong> Since there is no number in nums that is neither the maximum nor the minimum, we cannot select a number that satisfies the given condition. Therefore, there is no answer.
</pre>

<p><strong class="example">Example 3:</strong></p>

<pre>
<strong>Input:</strong> nums = [2,1,3]
<strong>Output:</strong> 2
<strong>Explanation:</strong> Since 2 is neither the maximum nor the minimum value in nums, it is the only valid answer.
