Address: poj 2516 I'm dizzy... This question comes up with the idea of separating each type of goods .. But I immediately gave up .. It seems that it is too time-consuming to request 50 fee streams .. Later, we decided to split the point. It took a long time to split it, and it had been TLE .. Even if it drops to 2600 points, it's also TLE .. Then I think of this separate method, and suddenly I feel that th

search path. Oh no, tle... t_t To reduce running time, I need to get rid of dupplicate calculation, so the first step is to find duplicate calculation. when finding ring, if the search path reach an vertex that not belong to sub_graph, but had been visited before, current strategy is to ignore this "wrong path" (because it dosen't lead to a ring), in fact, all arcs in this path cocould be deleted, all vertex cocould add to the sub_graph aft

Question link: http://acm.hust.edu.cn/vjudge/problem/viewProblem.action? Id = 47319 For a given sequence, it is required to determine a subsequence, ① so that all values in the subsequence can be divisible by one of the values, ② The subsequence range is as large as possible (R-l is as large as possible ). Solution: For requirement 1, it is not difficult to find that only min (L, R) = gcd (L, R) is required. GCD is l, Min is l, and r is the minimum value. For requirement 2, the traditional appro

, TLE, change it, and then TLE .. Several times later, I realized that common algorithms were hard to get through .. I have no idea how to change it... After reading the discussion, I learned that the Tarjan algorithm that requires strong-connected components is used. Baidu found Tarjan and it took a long time to understand it .. After reading Tarjan, I thought for more than an hour, wrote the code, and fin

look at question I, we will be the most followed by question a, so we get started with it, because the water above gave me the luck of water, I was so angry that I had to abuse the keyboard and sumit, TLE, and expected. So I think that good optimization can be improved, and a bunch of messy improvements seem to be right. So after soliciting comments from my teammates, I am doing well in sumit and Wa. I know wa, that is, it is impossible to use

In the internal competition, this question is sdut_2369. Map writes TLE. In other words, the OJ team members were sentenced to AC and me to TLE. Finally, the Captain concluded that this is a matter of character... Khan = _ = /// After the game, I wrote it with hash. The key is to handle conflicts and write it with the chain method. Finally, let's take a look at how it looks like an adjacent table. Maybe you

describes some knowledge about Euler's functions. 1. Definition: for a positive integer n, Phi (n) is a positive integer smaller than or equal to n, and the number of mutual quality with n. For example, Phi (8) = 4, because 1, 3, 5, 7 and 8 are mutually qualitative. 2. properties: 1) If p is a prime number, Phi (p) = p-1. 2) if n is the k power of prime p, Phi (n) = (p-1) * p ^ (k-1 ). Because all the multiples of p are mutually dependent on n. 3) the Euler's function is a product function. If
