// 1. Write a code snippet that sets a to an array of n random integers between 0
// (inclusive) and n (exclusive).
var a = new Array[Int](10)                //> a  : Array[Int] = Array(0, 0, 0, 0, 0, 0, 0, 0, 0, 0)
for(i <- 0 until a.length) a(i) = scala.util.Random.nextInt(10)
a                                         //> res0: Array[Int] = Array(9, 0, 5, 8, 6, 6, 3, 9, 0, 3)

// 2. Write a loop that swaps adjacent elements of an array of integers. For example,
// Array(1, 2, 3, 4, 5) becomes Array(2, 1, 4, 3, 5).
a = Array[Int](1,2,3,4,5)
a                                         //> res1: Array[Int] = Array(1, 2, 3, 4, 5)
