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
a = {}
ma = 0
m = []
for u in sys.stdin:
    i = int(u)
    if not (i in a):
        a[i] = 1
    else:
        a[i] += 1
    # ???????????§????????±???
    if ma <= a[i]:
        if ma < a[i]:
            ma = a[i]
            m.clear()
        m.append(i)
m = sorted(m)
for k in m:
    print(k)
