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"
]

題目

給你一個整數(shù)n. 從 1 到 n 按照下面的規(guī)則打印每個數(shù)：

• 如果這個數(shù)被3整除，打印fizz.
• 如果這個數(shù)被5整除，打印buzz.
• 如果這個數(shù)能同時被3和5整除，打印fizz buzz.

分析

較為簡單，就是一個分支問題

代碼

public class Solution {
    public List<String> fizzBuzz(int n) {
        List<String> res = new ArrayList<String>();
        for(int i=1;i<=n;i++) {
            if(i % 15 == 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;
    }
}
