Approach

Complexity

• Time: $O(n)$
• Space: $O(n)$

Code

class Solution:
    def maxFrequencyElements(self, nums: List[int]) -> int:
        data = Counter(nums)
        currMax = 0
        res = 0
 
        for key, freq in data.items():
            if freq > currMax:
                currMax = freq
                res = freq
            elif freq == currMax:
                res += freq
 
        return res
