LeetCode – HIndex (Java)
Given an array of citations (each citation is a nonnegative integer) of a researcher, write a function to compute the researcher's hindex. 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.
For example, given citations = [3, 0, 6, 1, 5], which 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, his hindex is 3.
Java Solution
public int hIndex(int[] citations) { Arrays.sort(citations); int result = 0; for(int i=0; i<citations.length; i++){ int smaller = Math.min(citations[i], citations.lengthi); result = Math.max(result, smaller); } return result; } 
<pre><code> String foo = "bar"; </code></pre>
