4.2.1 hdu1242 rescue A simple BFS has a bit of DP feeling in it. Because playing a guard will delay time, you cannot simply check whether it has searched a grid, if you can get to this point faster from this path, you need to update this point. # Include 4.2.2 hdu1548 a strange lift 4.2.3 hdu1372 knight moves Two BFs with no skills .. 4.2.4 escape from the maze with hdu1728 Every time you follow the ne
Hdu2717 In the question, N belongs to [1-100000] and cannot go out of 100000. At the beginning, n can always be written in half. This error is reported twice. In addition, the question is to find the minimum number of steps, or BFs. This question is purely an exercise. Question: Start Point and end point. You can take one step forward and one step backward. Analysis: BFS. Code: # Include Hdu1548 Still
Several questions are BFs, which have one-dimensional, two-dimensional, and three-dimensional In fact, they are all the same. What really needs to be considered is some status judgments and some conditions. For example, if you want to escape the maze, you can find the number of deflection directions, or you can join the team one by one without turning a line. The condition is: When this time turns less than the previous time, we can see that the score

Obtain the right vertex u in the output queue. If the vertex is not accessed, access the vertex and mark it as accessed. 5. Find the first adjacent node W of U. 6. If W does not exist, go to step 3; otherwise, run it cyclically. A. If W has not been accessed, add W to the queue first. B. F

It's easy to use a BFs. Pay attention to it and cut it over ~~ 6 minutes to complete code debugging. 5 minutes later, it's still amazing ~~~ The following is a problem with the HDU server code. the maximum time for each submission is 765 ms or a small value. Of course, it can be further optimized. For example, bit operation processing may take more than twice as long as it is too time-consuming to write. Code highlighting produced by Actipro CodeH
