The digitized slides will be represented by a rectangular grid of periods, '.', indicating empty space, and the capital letter 'X', indicating part of an object. Simple examples are An X in a grid square indicates that the entire grid square, including its boundaries, lies in some object....
NEERC2018A(bfs+dfs+贪心+记忆化) http://codeforces.com/contest/1070 题意:求出最小的正整数,使它满足数位和为s,且可以被d整除 一道不错的题。。 这个显然可以把(d,s)作为状态来存,可是数字太大存不下,但是存个长度还是可以的,然后直接做bfs之后就可以得到目标数字的长度了。。然而这个数字...
The most important points is,BFS starts visiting nodes from rootwhileDFS starts visiting nodes from leaves. So if our problem is to search something that is more likely to closer to root, we would prefer BFS. And if the target node is close to a leaf, we would prefer DFS. ...

As special cases, an empty graph, a single tree, and the discrete graph on a set of vertices (that is, the graph with these vertices that has no edges), are examples of forests. Graph ADT: field variables: Collection of vertices Collection of edges numOfVertices() numOfEdges() ...
