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: Accepted)

import sys

data = [0] * 101

for line in sys.stdin:
  try:
    n = int(line)
    data[n] += 1
  except:
    break
m = max(data)
for i in range(len(data)):
  if data[i] == m:
    print(i)
