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: Accepted)

arg = []
while (get = gets)
  arg << get.to_i
end
max = 0
suspection = []
temp = 0
count = 0
arg.sort.each{|i|
  if temp == i
    count += 1
    if max < count
      suspection = [i]
      max = count
    elsif max == count
      suspection << i
    end
  else
    temp = i
    count = 1
  end}
puts suspection
