题目描述 编程计算由“1”号围成的下列图形的面积.面积计算方法是统计1号所围成的闭合曲线中点的数目. 如图所示,在10*10的二维数组中,“1”围住了15个点,因此面积为15. 题目大意:对于给定的10*10的01矩阵,请问有多少个0被1包围了?(包围是指不能由上下左右通向边缘)本文来源于OIER博客,原文出处:http://www.oier.cc/ssoj2316%E9%9D%A2%E7%A7%AF/ 解题思路 图形学中Flood Fill是满水法填充,是用来填充区域的.就好比在一个地方一直到…

题目背景 oibh总部突然被水淹没了!现在需要你的救援…… 题目描述 oibh被突来的洪水淹没了>.<还好oibh总部有在某些重要的地方起一些围墙,用号表示,而一个封闭的号区域洪水是进不去的……现在给出oibh的围墙建设图,问oibh总部没被淹到的重要区域(由”0”表示)有多少. 输入输出格式 输入格式: 第一行是两个数,x和y(x,y<=500) 第二行及以下是一个由*和0组成的x*y的图. 输出格式: 输出没被水淹没的oibh总部的“0”的数量. 输入输出样例 输入样例#1: 样例输…
