Exercise: count words

• Count how many times each word appears in a given slice
• You can use this skeleton:

package main

import (
	"fmt"
)

func main() {
	celestialObjects := []string{"Moon", "Gas", "Asteroid", "Dwarf", "Asteroid", "Moon", "Asteroid"}
	fmt.Println(celestialObjects)

}

• Expected output:

[Moon Gas Asteroid Dwarf Asteroid Moon Asteroid]
Moon       2
Gas        1
Asteroid   3
Dwarf      1
