The frequency of an element is the number of times it occurs in an array.

You are given an integer array `nums` and an integer `k`. In one operation, you can choose an index of `nums` and increment the element at that index by `1`.

Return the maximum possible frequency of an element after performing at most `k` operations.

Example 1:

    Input: nums = [1,2,4], k = 5
    Output: 3
    Explanation: Increment the first element three times and the second element two times to make nums = [4,4,4].
    4 has a frequency of 3.

Example 2:

    Input: nums = [1,4,8,13], k = 5
    Output: 2
    Explanation: There are multiple optimal solutions:
    - Increment the first element three times to make nums = [4,4,8,13]. 4 has a frequency of 2.
    - Increment the second element four times to make nums = [1,8,8,13]. 8 has a frequency of 2.
    - Increment the third element five times to make nums = [1,4,13,13]. 13 has a frequency of 2.

Example 3:

    Input: nums = [3,9,6], k = 2
    Output: 1

Constraints:

- `1 <= nums.length <= 105`
- `1 <= nums[i] <= 105`
- `1 <= k <= 105`
