Fizz Buzz
题目
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 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

/**
* @param {number} n
* @return {string[]}
*/
export default function(n: number): string[] {
let results = ['1']
for (let i = 2; i <= n; i++) {
const isFizz = !(i % 3)
const isBuzz = !(i % 5)
if (isFizz && isBuzz) {
results.push('FizzBuzz')
} else if (isFizz && !isBuzz) {
results.push('Fizz')
} else if (isBuzz && !isFizz) {

} else {

}
}
return results
