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
a = {}
while True:
    try:
        n = int(raw_input())
        if n not in a:
            a[n] = 0
        a[n] += 1
    except EOFError:
        break
a = sorted(a.items(), key=lambda x:x[1], reverse = True)
for s in [k for k,v in a if v == a[0][1]]:
    print s
