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 Python3 (judge verdict: Wrong Answer)

import sys
from collections import Counter


if __name__ == '__main__':
    # ??????????????\???
    # data = [5, 6, 3, 5, 8, 7, 5, 3, 9, 7, 3, 4]
    data = []
    for line in sys.stdin:
        data.append(int(line.strip()))
    print(data)

    # ?????????????¢????
    c = Counter(data)
    max_freq = c.most_common(1)[0][1]  # ???????????????????????°????¨???¶
    modes = []
    for val, freq in c.most_common():
        if freq != max_freq:
            break
        modes.append(val)

    # ???????????¨???
    modes.sort()
    for i in modes:
        print(i)
