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.

Example

Input

5
6
3
5
8
7
5
3
9
7
3
4


Output

3
5
import sys

d={}
mode=0

while True:
  n = sys.stdin.readline()
  if not n: break
  n = int(n)
  if d.has_key(n):
    d[n] = d[n]+1
  else:
    d[n] = 1
  if mode < d[n]:
    mode = d[n]

for k in d.keys():
  if d[k] == mode:
    print(k)
