定义dfs(int x,int y)表示(x,y)到终点的最大权值和,最后的答案就是dfs(1,1). 为了避免重复搜索,我们开设一个数组dg[x][y]表示(x,y)点到终点的最大权值。 参考程序: #includeusing namespace std; int a[550][550],dg[550][550]; int n; int dfs(int x,int y) { if(dg[x][y]==-1)...

getInt putInt 有趣的使用case 跳过构造初始化 allocateInstance方法可能是有用的,当你需要在构造函数中跳过对象初始化阶段或绕过安全检查又或者你想要实例化哪些没有提供公共构造函数的类时就可以使用该方法。考虑下面的类: 代码语言:javascript 代码运行次数:0 ...
A regular expression, specified as a string, must first be compiled into an instance of this class. The resulting pattern can then be used to create a Matcher object that can match arbitrary java.lang.CharSequence character sequences against the regular expression. All of the state involved in...
