Subject: [PATCH] Fix Triangle example

The current example doesn't work, it prints out each *  on a new line.

```console
scala> def triangle(side: Int): Unit = {
     |          (1 to side) foreach { row =>
     |            (1 to row) foreach { col =>
     |              println("*")
     |            }
     |          }
     |        }
triangle: (side: Int)Unit

scala> triangle(4)
*
*
*
*
*
*

scala> def triangle2(side: Int): Unit = {
     |          (1 to side) foreach { row =>
     |            (1 to row) foreach { col =>
     | print("*")
     | }
     | print("\n")
     | }
     | }
triangle2: (side: Int)Unit

scala> triangle2(4)

 We can abstract out 4 into a parameter:
