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)

arry = [0]
arry.clear()

while line = gets.chomp
   break;
end

most_appear_val = [0]
appear_cnt = 0
for i in 1..100 do
  count = arry.count(i)
  if( appear_cnt < count )
    most_appear_val.clear()
    most_appear_val.push(i)
    appear_cnt = count
  elsif( appear_cnt == count )
    most_appear_val.push(i)
  end
end

puts most_appear_val
