412 fizz buzz

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

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"
]

没什么好说的，第一次裸考ibm的时候看过，也一次就写对了。主要注意的是要先判断FizzBuzz的情况，然后再分开fizz和buzz。

public List<String> fizzBuzz(int n) {
    List<String> res = new ArrayList<>();
    if (n < 1) {
        return res;
    }

    for (int i = 1; i <= n; i++) {
        if (i % 3 == 0 && i % 5 == 0) {
            res.add("FizzBuzz");
        } else if (i % 3 == 0) {
            res.add("Fizz");
        } else if (i % 5 == 0) {
            res.add("Buzz");
        } else {
            res.add(String.valueOf(i));
        }
    }

    return res;
}
