fizzbuzz.go

// fizzbuzz
// A program that counts from 1 to 100, replacing numbers divisible by 3 with "Fizz",
// those divisible by 5 with "Buzz", and those divisble by both 3 and 5 with "FizzBuzz".

package main

import "fmt"
import "strconv"

func main() {
	for i := 1; i <= 100; i++ {
		fmt.Println(fizzBuzz(i))
	}
}

func fizzBuzz(i int) (s string) {
	switch {
	case i%5 == 0 && i%3 == 0:
		return "FizzBuzz"
	case i%3 == 0:
		return "Fizz"
	case i%5 == 0:
		return "Buzz"
	}
	return strconv.Itoa(i)
