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.Collections;
import java.util.Map;
import java.util.Scanner;
import java.util.TreeMap;

class Main {

	public static void main(String[] args) {

		Scanner sc = null;
		Map<Integer, Integer> map = new TreeMap<Integer, Integer>();
		try {
			sc = new Scanner(System.in);
			while (sc.hasNextInt()) {
				int num = sc.nextInt();
				map.put(num, map.containsKey(num) ? map.get(num) + 1 : 1);
			}

			int maxValue = Collections.max(map.values());
			for (Map.Entry<Integer, Integer> entry : map.entrySet()) {
				if (maxValue == entry.getValue()) {
					System.out.println(entry.getKey());
				}
			}

		} finally {
			sc.close();
		}
	}
