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)

data = Array.new()
i = 0


while data[i] = gets do
	i += 1
end



j = 0

number = Array.new()
while out = data[j]
	out = out.chomp
	number[j] = out.to_i
	j += 1
end

ten = Array.new(100,0)
number = number.sort
score = number.uniq

i=0
j=0
k=0

for i in score do
	for j in number do
		if i == j
			ten[k] = ten[k] + 1
		end
	end
	k += 1;
end

max = ten.max

i = 0
k = 0

for i in ten do
	if i == max 
		 p score[k + 1]
	end
	k += 1
end
