H-Index II
Given an array of citations sorted in ascending order (each citation is a non-negative integer) of a researcher, write a function to compute the researcher's h-index. According to the definition of h-index on Wikipedia : "A scientist has index h if h of his/her N papers have at least h citations each, and the other N − h papers have no more than h citations each." Example: Input: citations = [0,1,3,5,6] Output: 3 Explanation: [0,1,3,5,6] means the researcher has 5 papers in total and each of them had received 0 , 1, 3, 5, 6 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, her h-index is 3 . Note: If there are several possible values for h , the maximum one is taken as the h-index. class Solution { ...
