Scala:Filter Array

This is a solution for the following assignment in hackerrank website  in refrence to functional programming

Objective :-

Filter a given array of integers and output only those values that are less than a specified value X. The output integers should be in the same sequence as they were in the input. You need to write a function with the recommended method signature for the languages mentioned below. For the rest of the languages, you have to write a complete code.

Input Format

The first line contains the delimiter  X.
The next lines B each contain an integer , which represents the elements of the list/array. You have to read the input to the End-Of-File.

Output Format

Print all the integers from the array that are less than the given upper limit  X in value on separate lines. The sequence should be the same as it was in the original array.

Solution :- 


object FilterArray extends App{
def f(delim:Int,arr:List[Int]):List[Int] =
{ val l = scala.collection.mutable.ListBuffer.empty[Int]
arr.foreach { i => {if (i < delim) l+=i } }




Output – List(2, 3, 4, 6, 7)
