    2592 - Maximize Greatness of an Array.

    Medium

    You are given a 0-indexed integer array nums. You are allowed to permute nums into a new array perm of your choosing.

    We define the greatness of nums be the number of indices 0 <= i < nums.length for which perm[i] > nums[i].

    Return the maximum possible greatness you can achieve after permuting nums.

    Example 1:

    Input: nums = 1,3,5,2,1,3,1

    Output: 4

    Explanation: One of the optimal rearrangements is perm = 2,5,1,3,3,1,1. At indices = 0, 1, 3, and 4, permi> numsi. Hence, we return 4.

    Example 2:

    Input: nums = 1,2,3,4

    Output: 3

    Explanation: We can prove the optimal perm is 2,3,4,1. At indices = 0, 1, and 2, permi> numsi. Hence, we return 3.

    Constraints:

    • <code>1 <= nums.length <= 10<sup>5</sup></code>

    • <code>0 <= numsi<= 10<sup>9</sup></code>
