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 collections
import sys
cntr = collections.Counter()
for line in sys.stdin:
    cntr[int(line)] += 1
lst = []
for k,v in cntr.items():
    lst.append((v,k))
lst.sort()
t = len(lst)-1
while t>0 and lst[t][0] == lst[t-1][0]:
    t -= 1
for i in range(t,len(lst)):
    print(lst[i][1])
