每日一题:412. Fizz Buzz

给你一个整数 n ,找出从 1 到 n 各个整数的 Fizz Buzz 表示,并用字符串数组 answer(下标从 1 开始)返回结果,其中:

answer[i] == "FizzBuzz" 如果 i 同时是 3 和 5 的倍数。
answer[i] == "Fizz" 如果 i 是 3 的倍数。
answer[i] == "Buzz" 如果 i 是 5 的倍数。
answer[i] == i (以字符串形式)如果上述条件全不满足。

示例 1:

输入:n = 3
输出:["1","2","Fizz"]

示例 2:

输入:n = 5
输出:["1","2","Fizz","4","Buzz"]

示例 3:

输入:n = 15
输出:["1","2","Fizz","4","Buzz","Fizz","7","8","Fizz","Buzz","11","Fizz","13","14","FizzBuzz"]

提示:

1 <= n <= 104

一道很简单的题,🥣。

题解:

impl Solution {
    pub fn fizz_buzz(n: i32) -> Vec<String> {
        let mut result:Vec<String> = Vec::new();
        for x in 1..=n {
            if x % 3 == 0 && x % 5 == 0 {
                result.push("FizzBuzz".to_string());
            }else if x % 3 == 0 {
                result.push("Fizz".to_string());
            }else if x % 5 == 0 {
                result.push("Buzz".to_string());
            }else {
                result.push(x.to_string());
            }
        }
        result
    }
}
