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 JavaScript (judge verdict: Accepted)

for(a=[],b=100;b--;)c=a[b]=0;require("fs").readFileSync("/dev/stdin","utf8").split('\n').some(function(i){if(+i)a[+i]++,c=a[+i]>c?a[+i]:c});a.some(function(i,j){if(i==c)console.log(j)})
