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 Scala (judge verdict: Accepted)

import io.StdIn.readLine

object Main extends App {
  val ns = Array.ofDim[Int](101)
  Iterator.continually(readLine)
    .takeWhile(_ != null)
    .foreach(e => {
      val n = e.toInt
      ns(n) += 1
    })
  val max = ns.max
  for(i <- 0 to 100 if ns(i) == max) println(i)
}
