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)

object Main extends App {
  val src: List[Int] = io.Source.stdin.getLines.map(_.toInt).toList

  val countedList: List[Int] = (for (i <- 1 to src.max) yield (src.count(_ == i))).toList

  println(countedList.zipWithIndex.collect { case (a, b) if a == countedList.max => b + 1 }.mkString("\n"))
}
