中文意思不解释. 很水,我本来想用switch处理字符串,然后编译不通过...原来switch只能处理整数型的啊,我都忘了. 然后就有了很挫的一大串if代码了... 代码: #include <iostream> #include <string> using namespace std; int digit(string str) { if (str == "zero") return 0; if (str == "one") return…

快速排序有一个特点,就是在排序过程中,我们会从序列找一个pivot,它前面的都小于它,它后面的都大于它.题目给你n个数的序列,让你找出适合这个序列的pivot有多少个并且输出来. 大水题,正循环和倒着循环一次,统计出代码中的minnum和maxnum即可,注意最后一定要输出'\n',不然第三个测试会显示PE,格式错误. #include <iostream> #include <cstdio> #include <algorithm> #include <map&…
