That is to say, your program runs slowly, and the result is later than 1 second to determine t

Question address: http://acm.hdu.edu.cn/showproblem.php? PID = 1, 3681 Bytes, BFs + binary + DFS. At first, I was too lazy and wanted to pass this question directly by BFs. As a result, TLE still wanted to use pruning or TLE. Helpless, use the second method to think of, the distance between the BFS pre-processing point and the point, then the length of the binary enumeration, DFS query can es

Finally, I began to take graph theory seriously. I have heard that I have been raising the group, and I have been moving very little. I have been learning some things since I started to improve my computer room. Template question link This is a question for finding negative loops. In theory, we all use spfa to judge negative loops. But I think Bellman-Ford is better. In addition, in this template question, the spfa has opened O2, and the bellman does not enable O2, which is faster than the spfa?

This is actually a simple simulation question, but after several wa, I finally wrote the floodfill Algorithm in it, and I should be very careful when writing a correct floodfill algorithm. The general process of floodfill is: Dye the start point and press it to the end of the team. Retrieve a point from the queueP X, Y) DetectionPThe surrounding area is (or, depending on whether the question requires eight or four directions), and the reachable points are dyed and pushed to the end of the t

putting the first layer with a maximum of colors. In part, this is correct, but the data range is large and cannot be simulated step by step. In addition, after a period of time, the most colors are not the most. N * (n + 1)/6 for each color is not considered. Then the remaining part is used as the extra ball. But the rest may not be enough, so we will set the heap number to 1, and the remaining balls will come out until they are satisfied. Unfortunately, this was written during the competition

the poor compatibility of poj with STL, I have never met the topic "tle" with STL... This is also the same, so it is not recommended. In fact, vector is very useful. With its features, it can automatically restore the site status when DFS returns to the previous step, the backtracking rule needs to manually restore the site status (in fact, 8 lines of code) DFS is used to find the path, backtracking (or vector) is used to restore the Board state, an

Relatives time limit: 1 second memory limit: 64 m Problemdescription Given n, a positive integer, how many positive integers less than or equal to N are relatively prime to n? Two integers A and B are relatively prime if thereare no integers x> 1, Y> 0, z> 0 such that a = xy and B = xz Z. Input There are several test cases. For each test case, standard input contains a line with n Output For each test case there shocould be single line of output answering the question posed above. Sample Input

It should be the single point update of the Line Segment tree. But at the beginning, it gave me the illusion that I was also drunk with a two-dimensional line segment tree. Tree [root]. x // X = L | r indicates that the root node represents the range of L-> r. Tree [root]. leftlen // indicates the maximum number of consecutive grids in the interval where the root node is located. What's even more depressing is that I use CIN cout to write it, even if it says "cin. sync_with_stdio (false)" or "

working on Stack and queue issues over the past few days. I just started out and want to do more! This is a simulated queue question! I used the linked list for a long time, because the linked list has not been used for a long time, but it is very troublesome to use the linked list. It is true that I have been entangled for a long time, but it is still written, and the code is not very clear, submit it again and then TLE, alas :-( Then I looked at o
