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)

#0028
import collections
a = list()
for i in range(100):
    try:
        a.append(int(input()))
    except:
        break
x = collections.Counter(a).most_common()[0][1]
z = collections.Counter(a).most_common()[0][0]

l = []

for j in range(len(collections.Counter(a).most_common())):
    y = collections.Counter(a).most_common()[j][1]
    v = collections.Counter(a).most_common()[j][0]
    if x == y:
        l.append(v)
    else:
        break
l.sort()
for k in range(len(l)):
    print(l[k])
