412. Fizz Buzz

Problem

Write a program that outputs the string representation of numbers from 1 to n.

But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and five output “FizzBuzz”.

Example:

n = 15,

Return:
[
    "1",
    "2",
    "Fizz",
    "4",
    "Buzz",
    "Fizz",
    "7",
    "8",
    "Fizz",
    "Buzz",
    "11",
    "Fizz",
    "13",
    "14",
    "FizzBuzz"
]

Summary

For multiples of 3, output "Fizz"; for multiples of 5, output "Buzz"; for multiples of 15, output "FizzBuzz"; otherwise, output the original number.

Solution Approach

Just follow the problem statement.

Code


package leetcode

import "strconv"

func fizzBuzz(n int) []string {
	solution := make([]string, n)
	for i := 1; i <= n; i++ {
		solution[i-1] = ""
		if i%3 == 0 {
			solution[i-1] += "Fizz"
		}
		if i%5 == 0 {
			solution[i-1] += "Buzz"
		}
		if solution[i-1] == "" {
			solution[i-1] = strconv.Itoa(i)
		}
	}
	return solution
}
