I believe that everyone has been playing anti-spam, and even three identical colors can be eliminated. This question also adds another condition, after each elimination, the system will fall down and move left to ask how many points you can score. Question: At the beginning, my first thought was BFS + DFS. Then, I decided to use MLE and finally read other people's code. Basically, it was DFS +

Brief Introduction to DFS and dfs
The so-called DFS is a search that does not hit the south wall and does not look back. The time complexity is O (V + E ).
The entire path from the start point to the end point can be calculated. During Algorithm Execution, a visit [vi] array is required to maintain access to each node, so that repeated access is avoided. Note th
Depth-first search (DFS) and depth-first search for dfs
Today, I reviewed the deep search of images for priority. I deeply felt that deep search is a plug-in, rather than a plug-in. It is simply a plug-in. dynamic planning cannot be done, and deep search is available, the greedy and greedy deep searches are made, and the collection and Topology Sorting cannot be done. The deep searches are all made. Unfortu
It is also a typical problem to find the connected block with DFS, and the process of multi-dimensional array connecting block is also called "seed filling".We add numbers to the connected blocks that are traversed each time, so that you can avoid a lattice access multiple times. The typical problem is the "eight-block problem". That is, any two squares are located adjacent to each other (up and down diagonally a total of eight positions), then in a c

In a network, the physical location of a shared file is distributed, and the user asks the other's shared path to get a clear picture of the shared resource. If you want to see a LAN full of shared files, you need to ask everyone, such an operation is too inconvenient.
Depending on the needs of your administrator, you can use the Distributed File System (DFS) that comes with Windows Server 2003. DFS can be
In POJ's first blood, a DFS solution, which has a lot of ingenious solutions, is worth learning.
