0412. FIzz Buzz (E)

Fizz Buzz (E)

题目

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

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"
]

题意

遍历1-n，如果是3的倍数则输出"Fizz"，5的倍数输出"Buzz"，既是3的倍数又是5的倍数输出"FizzBuzz"，否则输出原数字。

思路

直接遍历处理。

代码实现

Java

class Solution {
    public List<String> fizzBuzz(int n) {
        List<String> ans = new ArrayList<>();
        for (int i = 1; i <= n; i++) {
            if (i % 3 == 0 && i % 5 == 0) {
                ans.add("FizzBuzz");
            } else if (i % 3 == 0) {
                ans.add("Fizz");
            } else if (i % 5 == 0) {
                ans.add("Buzz");
            } else {
                ans.add("" + i);
            }
        }
        return ans;
    }
}
