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.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;

class Main{
    public static void main(String[] args) throws IOException{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        
        int[] data = new int[101]; // data[0]は使わない
        for(int i = 0; i < 101; i++){
            data[i] = 0;
        }

        String input;
        while((input = br.readLine()) != null){
            data[Integer.parseInt(input)]++;
        }

        int max = 0;
        for(int i = 0; i < 101; i++){
            if(data[i] > max){
                max = data[i];
            }
        }

        for(int i = 0; i < 101; i++){
            if(data[i] == max){
                System.out.println(i);
            }
        }
    }
}
