1、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"
-
]
2、代码实现
-
public class Solution {
-
public List<String> fizzBuzz(int n) {
-
if (n < 0)
-
return null;
-
List<String> list = new ArrayList<String>();
-
for (int i = 1; i <= n; ++i) {
-
if (i % 3 == 0 && i % 5 == 0) {
-
list.add("FizzBuzz");
-
}
-
else if (i % 3 == 0 && i % 5 != 0) {
-
list.add("Fizz");
-
}
-
else if (i % 3 != 0 && i % 5 == 0) {
-
list.add("Buzz");
-
} else {
-
list.add(String.valueOf(i));
-
}
-
}
-
return list;
-
}
-
}
3、总结
我当时写的时候把
for int = 0; i <= n; ++i
把i = 1开始就对了，因为你看题目输出，都是从1开始，所以不要惯性思维老是从i = 0 开始，i ＝0 ，i ％ 3 ＝＝ 0 ，i ％ 5 ＝＝0
所以以后写代码一定要注意i的初始位置。
