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)

process.stdin.on("data",function(c){
	var k=[],m=1,t=0,p;
	(c+"").trim().split("\n").sort(function(a,b){
		return a-b;
	})
	.map(function(n){
		p==n?t++:((t>m?(k=[p],m=t):t==m?(k.push(p),m=t):0),(t=0));
		p=n;
	});
	console.log(k.join("\n"));
}).resume();
