Problem 5: FizzBuzz | Array 1 Dimensional

Problem Description

Given a positive integer A, return an array of strings with all the integers from 1 to N. But for multiples of 3 the array should have “Fizz” instead of the number. For the multiples of 5, the array should have “Buzz” instead of the number. For numbers which are multiple of 3 and 5 both, the array should have “FizzBuzz” instead of the number.

Look at the example for more details.

Problem Constraints

  • 1 <= A <= 500000

Input Format

The first argument has the integer A.

Output Format

Return an array of string.

Example Input

Input 1:

A = 5

Example Output

Output 1:

[1 2 Fizz 4 Buzz]

Example Explanation

Explanation 1:

3 is divisible by 3 so it is replaced by “Fizz”. Similarly, 5 is divisible by 5 so it is replaced by “Buzz”.


public class Solution {
    public ArrayList<String> fizzBuzz(int A) {
        ArrayList<String> output = new ArrayList<>();
        for (int currentNumber = 1; currentNumber <= A; ++currentNumber ) {
            if (currentNumber % 15 == 0) {
                output.add("FizzBuzz");
            }
            else if (currentNumber % 5 == 0) {
                output.add("Buzz");
            }
            else if (currentNumber % 3 == 0) {
                output.add("Fizz");
            }
            else {
                output.add(Integer.toString( currentNumber ) );
            }
        }
        return output;
    }
}
