+// EXERCISE: Slice the numbers
+//
+//   We've a string that contains even and odd numbers.
+//
+//   1. Convert the string to an []int
+//
+//   2. Print the slice
+//
+//   3. Slice it for the even numbers and print it (assign it to a new slice variable)
+//
+//   4. Slice it for the odd numbers and print it (assign it to a new slice variable)
+//
+//   5. Slice it for the two numbers at the middle
+//
+//   6. Slice it for the first two numbers
+//
+//   7. Slice it for the last two numbers (use the len function)
+//
+//   8. Slice the evens slice for the last one number
+//
+//   9. Slice the odds slice for the last two numbers
+//
+//
+// EXPECTED OUTPUT
+//   go run main.go
+//
+//     nums        : [2 4 6 1 3 5]
+//     evens       : [2 4 6]
+//     odds        : [1 3 5]
+//     middle      : [6 1]
+//     first 2     : [2 4]
+//     last 2      : [3 5]
+//     evens last 1: [6]
+//     odds last 2 : [4 6]
+//
+//
+// NOTE
+//
+//  You can also use my prettyslice package for printing the slices.
+//
+//
+// HINT
+//
+//  Find a function in the strings package for splitting the string into []string
