Problem Statement

Given an array of positive integers named nums, return the total frequencies of the elements in nums that have a maximum frequency.

The frequency of an element is defined as the number of times that element is repeated in the array.

Examples

Example 1:

  • Input: nums = [3, 2, 2, 3, 1, 4]
  • Output: 4
  • Explanation: Both 2 and 3 appear twice, which is the highest frequency. So, the total frequency is 2 + 2 = 4.

Example 2:

  • Input: nums = [5, 5, 5, 2, 2, 3]
  • Output: 3
  • Explanation: The number 5 appears three times, which is the highest frequency. So, the total frequency is 3.

Example 3:

  • Input: nums = [7, 8, 8, 7, 9, 9]
  • Output: 6
  • Explanation: All elements appear twice. So, total maximum frequency is 2 + 2 + 2 = 6.

Constraints:

  • 1 <= nums.length <= 100
  • 1 <= nums[i] <= 100
