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.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Map;
import java.util.HashMap;

public class Main{
	

	
	public static void main(String[] args) throws IOException{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		int num[] = new int[101];
		String price;
		
		while((price = br.readLine()) != null){
			num[Integer.parseInt(price)]++;
		}
		
		int max = -1;
		
		for(int i = 1;i <= 100;i++){
			
			if(max<num[i]){
				max = num[i];
			}
			
		}
		
		for(int i = 1;i <= 100;i++){
			
			if(max == num[i]){
				System.out.println(i);
			}
			
		}
	}
