Congradulations, you have passed the first step in interviewing with us. The next phase will be to take short exercises in programming.

In this exercise we would like you to exprience with Scala programming language which is a functional programming language.

Follow the instructions of the exam below, and produce the given results in Scala. You may use Pull requests from your Git account or send it to us back on e-mail

Please take your time, the exam is not hard and we don't need the result. We need to see how you code.

The first you have to do is install "SBT" [http://www.scala-sbt.org] on your machine.
The second is implement Scala code and test.

There's some Scala information here: http://www.scala-lang.org/documentation/getting-started.html

1. Create diamond shape follow by "n". (n is odd value only)
val d3 = DiamondShape(3)
d3.printDiamond() 
----------------------------------------------------------------
  +
+ + +
  +


val d5 = DiamondShape(5)
d5.printDiamond()
----------------------------------------------------------------
    +
  + + +
+ + + + +
  + + +
    +

Create butterfly shape follow by "n". (n is even value only)
val b2 = ButterflyShape(2)
b2.printButterfly() 
----------------------------------------------------------------
+       +
+ + - + +
+       +


val b4 = ButterflyShape(4)
b4.printButterfly()
----------------------------------------------------------------
+               +
+ +           + +
+ + +       + + +
+ + + + - + + + +
+ + +       + + +
+ +           + +
+               +

1. SBT

• JDK 1.7 up
• GIT

 > sbt compile
 
 > sbt test
