[LeetCode] Fizz Buzz 嘶嘶嗡嗡

2023年6月29日 235次阅读 来源: Grandyang

 

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"
]

 

这道题真心没有什么可讲的，就是分情况处理就行了。

 

class Solution {
public:
    vector<string> fizzBuzz(int n) {
        vector<string> res;
        for (int i = 1; i <= n; ++i) {
            if (i % 15 == 0) res.push_back("FizzBuzz");
            else if (i % 3 == 0) res.push_back("Fizz");
            else if (i % 5 == 0) res.push_back("Buzz");
            else res.push_back(to_string(i));
        }
        return res;
    }
};
