基础算法-Fizz Buzz

Fizz Buzz

• 如果 n 是3的倍数，输出"Fizz",如果 n 是5的倍数，输出“Buzz".如果 n 同时是3和5的倍数，输出 "FizzBuzz"

function fizzBuzz(int $n): array
{
    $result = [];
    //初始化为数字
    for ($i = 1; $i <= $n; $i++) {
        $result[$i] = "";
    }
    //如果是3的倍数,改为Fizz
    for ($i = 2; $i < $n; $i += 3) {
        $result[$i] = "Fizz";
    }
    //如果是5的倍数，改为Buzz
    for ($i = 4; $i < $n; $i += 5) {
        $result[$i] = "Buzz";
    }
    //如果是3和5的倍数，也就是15倍改为FizzBuzz
    for ($i = 14; $i < $n; $i += 15) {
        $result[$i] = "FizzBuzz";
    }
    return $result;
}
