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 Ruby (judge verdict: Wrong Answer)

a = []

loop do
	s = gets
	if !s then break; end
	a.push(s.to_i)
end

ary = []

for i in a.min..a.max do
	if !ary.max or a.count(i) >= ary.max()
		if !ary.max or a.count(i) > ary.max() then ary = []; end
		ary.push(i)
	end
end

ary.each do |v|
	puts v
end
