这题是上一题的升级版 关键在于条形图的构造,逐行处理输入的矩阵,遇到'F'则在上一次的条形图基础上再加1,遇到'R'则置为0 然后用上一题的算法,求每行对应条形图的最大矩阵的面积. 另外:本来是debug都不用就1A的节奏.可在输入数据上,一开始我用的是scanf读入字符 和 getchar跳过无效字符,在测试数据上是没有问题的,但一交上去就WA掉了. 看到别人的代码使用cin读入的.其实,如果输入数据不太大的话,cin还是比较放心好用的. //#define LOCAL #include <i…

题意:是二维的1506,即在1506的基础上,再加一个for循环,即从第一行到最后一行再扫一遍--- 自己写的时候,输入的方法不对---发现输不出结果,后来看了别人的----@_@发现是将字母和空格当成一个字符串来输入的. #include<iostream> #include<cstdio> #include<cstring> #include<algorithm> using namespace std; int h[1010][1010],l[1010…

最大01子矩阵和,就是一个矩阵的元素不是0就是1,然后求最大的子矩阵,子矩阵里的元素都是相同的. 这个题目,三个oj有不同的要求,hoj的要求是5s,poj是3秒,hdu是1秒.不同的要求就对应不同的难度,不同的逼格. 先看最low的, HOJ 1664 5秒钟的时间,够长了.我很容易想到可以最大子矩阵和来求解,二者本来就很像,关于最大子矩阵和这个博客里有介绍 最大子矩阵和 这里我们可以把F变成1,把R变成负无穷大,这样求解最大子矩阵和就可以得到答案 #include <iostream> #…
