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)

a=[]
try:
    while True:
        a.append(int(input()))
except EOFError:
    pass
lis=[0]*101
for n in a:
    lis[n] +=1
for n in range(len(a)):
    if lis[n]==max(lis):
        print(n)
