You are given an integer array nums.
Return true if the frequency of any element of the array is prime, otherwise, return false.
The frequency of an element x is the number of times it occurs in the array.
A prime number is a natural number greater than 1 with only two factors, 1 and itself.
Examples
Example 1
Input: nums = [1,2,3,4,5,4]
Output: true
Explanation:
4 has a frequency of two, which is a prime number.
Example 2
Input: nums = [1,2,3,4,5]
Output: false
Explanation:
All elements have a frequency of one.
Example 3
Input: nums = [2,2,2,4,4]
Output: true
Explanation:
Both 2 and 4 have a prime frequency.
Constraints
1 <= nums.length <= 100
0 <= nums[i] <= 100
