A. Easy h-index
The h-index of an author is the largest h where he has at least h papers with citations not less than h.
Bobo has published many papers. Given a0,a1,a2,…,an which means Bobo has published ai papers with
itations exactly i, find the h-index of Bobo.
Input
The input consists of several test cases and is terminated by end-of-file.
The first line of each test case contains an integer n. The second line contains (n+1) integers a0,a1,…,an.
Output
For each test case, print an integer which denotes the result.
Constraint
• 1≤ n ≤2·105 • 0≤ ai ≤109 • The sum of n does not exceed 250,000.
Sample Input
1
1 2
2
1 2 3
3
0 0 0 0
Sample Output
1
2
0
题意:给定被引用次数为 0n 的论文分别有几张,找到最大的 h,满足被引用次数大于等于 h 的论文至少有 h 张0 遍历找到第一个满足条件的 h
思路:在区间 [0,n] 内二分答案;或直接从 n
后 AC 代码
