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 Python (judge verdict: Accepted)

dic = {}
while True:
    try:
        num = int(raw_input())
        if not num in dic:
            dic[num] = 1
        else:
            dic[num] = dic[num] + 1
          
    except EOFError:
        max_num = 0
        index = 0
        for k, v in sorted(dic.items(), key=lambda x: x[1], reverse=True):
            if index == 0:
                max_num = v
            if max_num != v:
                break
            print k
            index += 1
        break
