hdu 5386 Cover Description You have an matrix.Every grid has a color.Now there are two types of operating: L x y: for(int i=1;i<=n;i++)color[i][x]=y; H x y:for(int i=1;i<=n;i++)color[x][i]=y; Now give you the initial matrix and the goal matrix.There…
题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5386 题目大意:给一个初始矩阵(n×n).一个目标矩阵(n×n)和m个操作,要求找到一种操作顺序,使初始矩阵变成目标矩阵.操作共有两种,如下: L x y: 把当前矩阵第x列的数全变为y H x y: 把当前矩阵第x行的数全变为y 输入格式:先输入case数T,每个case第一行是两个整数n和m,接下来n行输入初始矩阵,再下来n行输入目标矩阵.最后m行输入操作. 1≤color[i][j]≤n,co…
