Algorithms

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

Return the selected integer.

&nbsp;
Example 1:

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

Example 2:

<pre>
Input: nums = [1,2]
Output: -1
Explanation: 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>

Example 3:

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

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= nums.length &lt;= 100</code></li>
	<li><code>1 &lt;= nums[i] &lt;= 100</code></li>
	<li>All values in <code>nums</code> are distinct</li>
</ul>
