考试题（已解决） 就一个WA啊！ 正确答案： 我的答案：

#include <iostream> #include <vector> #include <climits> using namespace std; int main() { int n; cin >> n; vector<int> a(n + 2), b(n + 2); for (int i = 1; i <= n; ++i) cin >> a[i]; for (int i = 1; i <= n; ++i) cin >> b[i]; }

输入三个数字，随便输 主要还是看代码。

进制 二进制：0b开头，例如 int a = 0b1110; 八进制：0开头，例如 int b = 0173; 十六进制：0x开头，例如 int c = 0x10c. 十进制转N进制 整数：短除法，将余数逆序排列即可。 小数：整数小数分开处理，小数部分乘以n，取整数部分，再用小数部分继续乘，直到等于一。 枚举算法 三要素：枚举对象，枚举条件与枚举范围 枚举排列 复杂度：O(n!) 测速代码 二进制子集枚举 埃氏筛 复杂度：O(log(log n))
