Write a function that:
- returns "Fizz" for multiples of 3
- returns "Buzz" for multiples of 5
- returns "FizzBuzz" for multiples of both 3 and 5
Any other number should return the number as string.
export function fizzBuzz(input: number): string {
const output: string = `${input % 3 === 0 ? "Fizz" : ""}${input % 5 === 0 ? "Buzz" : ""}`;
return output.length > 0 ? output : input.toString(10);
