要求:
给你一个整数n. 从 1 到 n 按照下面的规则打印每个数:
如果这个数被3整除,打印fizz.
如果这个数被5整除,打印buzz.
如果这个数能同时被3和5整除,打印fizz buzz.
样例
比如 n = 15, 返回一个字符串数组:
[
"1", "2", "fizz",
"4", "buzz", "fizz",
"7", "8", "fizz",
"buzz", "11", "fizz",
"13", "14", "fizz buzz"
]
水题,就贴一下代码:
class Solution { public: /** * param n: As description. * return: A list of strings. */ vectorfizzBuzz(int n) { vectorresults; for (int i = 1; i <= n; i++) { if (i % 15 == 0) { results.push_back("fizz buzz"); } else if (i % 5 == 0) { results.push_back("buzz"); } else if (i % 3 == 0) { results.push_back("fizz"); } else { results.push_back(to_string(i)); } } return results; } };
