解题思路:矩阵快速幂模板题,见代码: #include<cstdio> #include<cstring> #include<algorithm> using namespace std; ; #define mod 9973 int t, n, k; struct MT{ int m[maxn][maxn]; }; MT Mul(MT a, MT b) { MT res; memset(res.m, , sizeof(res.m)); ; i < n; i++)…
Queues and Priority Queues are data structures which are known to most computer scientists. The Queue occurs often in our daily life. There are many people lined up at the lunch time. Now we define that ‘f’ is short for female and ‘m’ is short for…
