For this Question: Given an array of citations (each citation is a non-negative integer) of a researcher, write a program 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."

Note: If there are several possible values for h, the maximum one is taken as the h-index.Input contains a single integer denoting the size of array.
The next line contains an array of integers, i.e., an array of citations

Constraints:
1 <= n <= 10^3
1 <= A[i] <= 10^3Output a single integer denoting the h-index.Input:
5
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, her h-index is 3., I have written this Solution Code: import java.io.*;
import java.util.*;



class Main {
    public static void main (String[] args) throws Exception{


         InputStreamReader reader = new InputStreamReader(System.in);
        BufferedReader br = new BufferedReader(reader);

        int sizeOfArray = Integer.parseInt(br.readLine());

        String[] str = br.readLine().trim().split(" ");
        int[] arr = new int[str.length];
        for(int i=0; i<arr.length; i++){
            arr[i] = Integer.parseInt(str[i]);
        }


        boolean bl = false;
        for(int i=arr.length-1; i>=0; i--){
            int count = 0;
            for(int j=0; j<arr.length; j++){
                if(arr[j]>=i+1){
                    count++;
                }
            }
            if(count>=i+1){
                System.out.println(i+1);
                bl = true;
                break;
            }
        }
        if(bl==false){
            System.out.println(0);
        }
    }
}, In this Programming Language: Java, Now tell me if this Code is compilable or not?
