 ## Description
+You are given an array `nums` consisting of **positive** integers.
+
+Return the **total frequencies** of elements in `nums` such that those elements all have the **maximum** frequency.
+
+The **frequency** of an element is the number of occurrences of that element in the array.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: nums = [1,2,2,3,1,4]
+Output: 4
+Explanation: 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.
 ```

-Count Elements With Maximum Frequency
-```go
 ```
-
+Input: nums = [1,2,3,4,5]
+Output: 5
+Explanation: 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.
