Count Elements With Maximum Frequency
<p>You are given an array <code>nums</code> consisting of <strong>positive</strong> integers.</p>

<p>Return <em>the <strong>total frequencies</strong> of elements in</em><em> </em><code>nums</code>&nbsp;<em>such that those elements all have the <strong>maximum</strong> frequency</em>.</p>

<p>The <strong>frequency</strong> of an element is the number of occurrences of that element in the array.</p>

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

<pre>
<strong>Input:</strong> nums = [1,2,2,3,1,4]
<strong>Output:</strong> 4
<strong>Explanation:</strong> The elements 1 and 2 have a frequency of 2 which is the maximum frequency in the array.
So the number of elements in the array with maximum frequency is 4.
</pre>

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

<pre>
<strong>Input:</strong> nums = [1,2,3,4,5]
<strong>Output:</strong> 5
<strong>Explanation:</strong> All elements of the array have a frequency of 1 which is the maximum.
So the number of elements in the array with maximum frequency is 5.
</pre>

<p><strong>Constraints:</strong></p>

<ul>
	<li><code>1 &lt;= nums.length &lt;= 100</code></li>
	<li><code>1 &lt;= nums[i] &lt;= 100</code></li>
</ul>
