这题做的一把鼻涕一把泪，果断考虑不周555Problem Description推箱子是一个很经典的游戏.今天我们来玩一个简单版本.在一个M*N的房间里有一个箱子和一个搬运工,搬运工的工作就是把箱子推到指定的位置,注意,搬运工只能推箱子而不能拉箱子,因此如果箱子被推到一个角上(如图2)那么箱子就不能再被移动了,如果箱子被推到一面墙上,那么箱子只能沿着墙移动.现在给定房间的结构,箱子的位置,搬运工的位置和箱子要被推去的位置,请你计算出搬运工至少要推动箱子多少格.Input输入数据的第一行是一个整数T(1 2 #include 3 using namespace std; 4 const ...

STL的堆操作STL里面的堆操作一般用到的只有4个:make_heap();、pop_heap();、push_heap();、sort_heap();他们的头文件函数是#include 首先是make_heap();函数原型是：void make_heap(first_pointer,end_pointer,compare_function);一个参数是数组或向量的头指针，第二个向量是尾指针。第三个参数是比较函数的名字。在缺省的时候，默认是大跟堆。（下面的参数都一样就不解释了）作用：把这一段的数组或向量做成一个堆的结构。范围是(first,last)然后是pop_heap();它的函数原型是 Read More

Problem Description某省自从实行了很多年的畅通工程计划后，终于修建了很多路。不过路多了也不好，每次要从一个城镇到另一个城镇时，都有许多种道路方案可以选择，而某些方案要比另一些方案行走的距离要短很多。这让行人很困扰。现在，已知起点和终点，请你计算出要从起点到终点，最短需要行走多少距离。Input本题目包含多组数据，请处理到文件结束。 每组数据第一行包含两个正整数N和M(0 2 const int MAX = 10000; 3 int n,m,map[200][200]; 4 5 int Dijkstra(int s,int e) 6 { 7 if(s==e) 8 ...

Problem DescriptionIgnatius bought a land last week, but he didn't know the area of the land because the land is enclosed by a parabola and a straight line. The picture below shows the area. Now given all the intersectant points shows in the picture, can you tell Ignatius the area of the land?No Read More

这个速度比分步快一点，内存占的稍微多一点Problem DescriptionSolitaire is a game played on a chessboard 8x8. The rows and columns of the chessboard are numbered from 1 to 8, from the top to the bottom and from left to right respectively. There are four identical pieces on the board. In one move it is allowed to: > mov Read More

Map是c++的一个标准容器，她提供了很好一对一的关系，在一些程序中建立一个map可以起到事半功倍的效果，总结了一些map基本简单实用的操作！1.map最基本的构造函数；mapmapstring; mapmapint; mapmapstring; mapmapchar; mapmapchar; mapmapint；2. map添加数据；map maplive; maplive.insert(pair(102,"aclive")); maplive.insert(map::value_type(321,"hai")); maplive[112]=" Read More
