矩阵快速幂. 样例是这样构造矩阵的: 矩阵很好构造,但是500*500*500*logk的复杂度显然是无法通过这题的. 其实本题构造出来的矩阵是一个循环矩阵,只需直到第一行或者第一列,即可直到整个矩阵是怎么样的. 所以,中间计算的时候,需要直到第一行是什么即可,即1*n的矩阵乘n*n的矩阵.时间复杂度o(n*n*logk) #include<cstdio> #include<cstring> #include<cmath> #include<vector>…

题目大意: 手机在蜂窝网络中的定位是一个基本问题.如果蜂窝网络已经得知手机处于c1, c2,-,cn这些区域中的一个.最简单的方法是同一时候在这些区域中寻找手机.但这样做非常浪费带宽. 因为蜂窝网络中能够得知手机在这不同区域中的概率.因此一个折中的方法就是把这些区域分成w组,然后依次訪问.比方.已知手机可能位于5个区域中,概率分别为0.3.0.05.0.1.0.3和0.25,w=2,则一种方法是先同一时候訪问{c1,c2,c3},再同一时候訪问{c4,c5},訪问区域数的数学期望为3*(0.3+…

题目传送门 题意:训练指南P186 分析:主要为了熟悉STL中的stack,queue,priority_queue,尤其是优先队列从小到大的写法 #include <bits/stdc++.h> using namespace std; int main(void) { int n; while (scanf ("%d", &n) == 1) { stack<int> sta; queue<int> que; priority_queue&…

做道水题凑凑题量,=_=||. 直接用STL里的queue.stack 和 priority_queue模拟就好了,看看取出的元素是否和输入中的相等,注意在此之前要判断一下是否非空. #include <bits/stdc++.h> using namespace std; void scan( int &x ) { char c; ' ); x = c - '; + c - '; } + ; int t[maxn], d[maxn]; bool is_queue(int n) { q…

题意:给你n个操做,判断是那种数据结构. #include<iostream> #include<cstdio> #include<cstdlib> #include<stack> #include<queue> using namespace std; int n; ],u[]; int ck_q() { //cout<<"!!"<<endl; queue<int>s; ; i<n;…

思路:分别定义栈,队列,优先队列(数值大的优先级越高).每次放入的时候,就往分别向三个数据结构中加入这个数:每次取出的时候就检查这个数是否与三个数据结构的第一个数(栈顶,队首),不相等就排除这个数据结构,可以用三个标志变量来标志可能的数据结构. 注意:可能会出现数据结构为空的情况,要先判断非空才能取元素. AC代码 #include <stdio.h> #include <stack> #include <queue> using namespace std; //分别…
