Challenge 2 — Solution

Task: Create a slice named words containing 6 short strings of your
choice. Print the first 3 using slicing syntax, then print the last
3 using slicing syntax, without using any literal index numbers
higher than what's needed for each.

package main

import "fmt"

func main() {
	words := []string{"go", "run", "build", "test", "fmt", "package"}

	fmt.Println(words[:3])
	fmt.Println(words[3:])
}


Expected output:

[go run build]
[test fmt package]

Notes:
- words[:3] omits the start index, which defaults to 0 — equivalent
  to words[0:3] but shorter.
- words[3:] omits the end index, which defaults to the slice's full
  length — equivalent to words[3:6] but doesn't hard-code the total
  count, so it would still work correctly if words had more or fewer
  elements.
- Both slicing expressions return NEW slices; the original words
  slice itself is unchanged by either one.
