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)

numarry = Array.new(100,0)

x = gets
until x.nil?
 y = x.chomp.to_i
 indexy = y - 1
 numarry[indexy] += 1
 x = gets
end

arraymax = numarry.max

arryindex = numarry.each_index.select{|i| numarry[i] == arraymax}

k = 0
while k < arryindex.length
 truenum = arryindex[k] + 1
 puts truenum
 k += 1
end
