题目链接:Codeforces 441C Valera and Tubes 没看到r >= 2一直错.让前几个管子占用2个格子.最后一个把剩下的都占用了.假设问题有解.这样做一定有解.其它策略就不一定了(比方让某个管子占用了3个格子.而总共同拥有四个格子,两个管子). #include <iostream> #include <cstdio> using namespace std; int main() { int n, m, k; scanf("%d%d%d&q…

贪心算法,每条路径最短2格,故前k-1步每次走2格,最后一步全走完 由于数据比较小,可以先打表 #include <iostream> #include <vector> #include <algorithm> #include <utility> using namespace std; typedef pair<int,int> Point; int main(){ ; cin >> n >> m >>k…

http://codeforces.com/contest/441/problem/C 题意:有n×m个方格,然后把这些方格分成k部分,每个部分内的方格的坐标满足|xi - xi + 1| + |yi - yi + 1| = 1,且每一个部分内的方格数>=2,输出其中的一种方案. 思路:贪心,先让k-1部分,每一部分占2个方格,依次按照蛇形划分,剩余划分到最后一个内. #include <cstdio> #include <iostream> #include <cma…

题目链接:http://codeforces.com/problemset/problem/441/C 题目意思:将n * m 的矩阵分成 k 堆.每堆是由一些坐标点(x, y)组成的.每堆里面至少由 >= 2 个坐标点组成,这些坐标点还需要满足: |xi - xi + 1| + |yi - yi + 1| = 1 .这个等式表示遍历堆里面的坐标好像蛇形那样走,也就是坐标点与坐标点之间需要相邻!还有一个条件就是,每个坐标点只能用一次. 做了一整天= =.改了一个问题,另一个问题又出现了.终于被一…
