Problem:
Mode Value

Your task is to write a program which reads a sequence of integers and prints mode values of the sequence.
The mode value is the element which occurs most frequently.

Input

A sequence of integers ai (1 ≤ ai ≤ 100). The number of integers is less than or equals to 100.

Output

Print the mode values. If there are several mode values, print them in ascending order.

Sample Input

5
6
3
5
8
7
5
3
9
7
3
4

Output for the Sample Input

3
5

For example, 3 and 5 respectively occur three times, 7 occurs two times, and others occur only one. So, the mode values are 3 and 5.

Solution in JAVA (judge verdict: Accepted)

import java.io.*;
import java.util.*;
public class Main {
	public static void main(String args[]) throws IOException {
		BufferedReader r = new BufferedReader(new InputStreamReader(System.in));
		int[] arr = new int[100];
		while(true) {
			String s = r.readLine();
			if(s == null) break;
			arr[Integer.valueOf(s) - 1]++;
		}
		int max = 0;
		for(int a : arr) {
			max = Math.max(a, max);
		}
		ArrayList<Integer> list = new ArrayList<Integer>();
		for(int i = 0; i < arr.length; i++) {
			if(arr[i] == max) {
				list.add(i + 1);
			}
		}
		Collections.sort(list);
		for(int l : list) {
			System.out.println(l);
		}
	}
}
