n papers have at least h citations each, and the other
n − h papers have no more than
h citations each.
If there are several possible values for

Input: citations = [3,0,6,1,5] Output: 3 Explanation: [3,0,6,1,5] means the researcher has 5 papers in total and each of them had received 3, 0, 6, 1, 5 citations respectively. Since the researcher has 3 papers with at least 3 citations each and the remaining two with no more than 3 citations each, their h-index is 3.
Input: citations = [1,3,1] Output: 1
n == citations.length
1 <= n <= 5000
0 <= citations[i] <= 1000
