Problem:
Small, Large, or Equal

Write a program which prints small/large/equal relation of given two integers a and b.

Input

Two integers a and b separated by a single space are given in a line.

Output

For given two integers a and b, print

a < b

if a is less than b,

a > b

if a is greater than b, and

a == b

if a equals to b.

Constraints

-1000 ≤ a, b ≤ 1000

Sample Input 1

1 2

Sample Output 1

a < b

Sample Input 2

4 3

Sample Output 2

a > b

Sample Input 3

5 5

Sample Output 3

a == b

Solution in Scala (judge verdict: Wrong Answer)

import scala.io.Source

object Main{
  def main(args: Array[String]){
    val list =
      for{
        in <- Source.stdin.getLines.toList
      } yield in.map(_.toInt).toList

    boc(list.flatten)
  }

  def boc(a: List[Int])={
    if(a(0) - a(1) == 0) println("a == b")
    else if(a(0) - a(1) > 0) println("a > b")
    else if(a(0) - a(1) < 0) println("a < b")
    else println()
  }
}
