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.util.Scanner;

class Main {
	public static void main(String[] args){
		Scanner cin = new Scanner(System.in);
		int [] x = new int[110];
		int i = 0;
		int a = 0;
		
		while (cin.hasNext()){
			i = cin.nextInt();
			x[i]++;
		}
		
		for (i = 0; i < 100; i++){
			if (a < x[i]){
				a = x[i];
			}
		}
		for (i = 0; i < 100; i++){
			if (a == x[i]){
				System.out.println(i);
			}
		}
	}
}
