Link to the Q A 1444-knowledge for the masses Given R and l, r indicates that there are R rows, and l indicates the maximum length of a row.For each row, n is given, followed by the number of n. If arr [I] is 0, it indicates space and length is 1. Otherwise, it indicates the shelf and length is arr [I]. Now, I want to move from the top to the bottom and ask to move at least a few bookshelves and output the path coordinates that can be passed. Solution: C [I] indicates how many lines can pass th

So the water's 01 backpack actually made me wa seven times. I started to understand the incorrect question and reversed the primary-secondary relationship. The most important premise is the total number of tracks, followed by the longest total time of songs. Question: There is still a t second left in the KTV room. You can select several songs from N favorite songs (each song can only be sung once and it must be sung once ), then at least one second is left to sing the first 678 second song. If

Question Link A piece of paper, which is folded from right to left each time. After the discount, it is opened, so that each crease is naturally 90 degrees. Output shape. Idea: Simulate discount ...... Each fold is imagined as dividing a piece of paper into a front and a back. Maintain the left and direction, and then output. There are a lot of details. Code: # Include Va 177: Paper Folding (simulate Grade D)

Question: Calculate the eight queens that must pass through the designated time. Analysis: search. Because eight queens only have 92 groups of solutions, they can calculate 92 groups of solutions directly, and then query and output the solutions. Here I use bitwise operations to calculate the eight queens and reduce the amount of code. First, consider the impact of a Queen. The relationship between the next attack and the last attack is as follows: A queen will influence two oblique directions (

Given the weight of N items, the size of the backpack is M. A backpack can hold up to two items. Ask how many backpacks at least. Idea: greedy, maximum, and minimum. If this is not the case, the greatest one must be lonely for life. Otherwise, the rows are accompanied. Code: #include Va 1149: bin packing (Greedy)

Alice and Bob are playing games again !!!! In the beginning, the former has a Yuan, and the latter has B yuan. Each time you play, the probability that each person wins is half-open. If C is the minimum value of A and B, then each time you play, if anyone loses, the winner is C yuan. Ask Alice the probability of winning and the expected number of game disks! Thought: It looks like it will be iterated! The formula is not good... The probability of discovery is 0.5, and the error range is 1e-5.

Question: equation x = p * floor (x ÷ K) + Q * Ceil (x ÷ K) given X and K, evaluate a group of valid p and q. Analysis: number theory. Set x = m * k + N (where n = x mod k ); If n = 0: x = m * k, floor (x ÷ K) = Ceil (x ÷ K) = M, x = p * m + Q * m, make P = K, q = 0; If n = 0: x = m * k + N, Ceil (x ÷ K) = m + 1, floor (x ÷ K) = M, x = (p + q) * m + Q, In this case, make p + q = K, q = N (because n Note: p and q can be exchanged when X is divisible by K. #include

For each vertex, if a son cannot maintain the edge, it is not feasible. Otherwise, try to let the son maintain the edge right. If not, he can only let the father bear it. #include

Ndk r8b was installed recently, but a large number of warnings are displayed when ndk-build is started in cygwin. So, Google it first to find the fuzzy answer. We can see from the ndk download website that ndkr8b has indeed updated the C ++ compiler. In addition, according to the introduction on the internet, there will be no such warning when using ndk R8. Well, I didn't try it. I guess OK (because the author said he did it himself ).The following content is also obtained:David Turner (from the

The difficulty of the provincial competition in the year before was that the stone was not well handled. Later I read the summary of Yang Shen's provincial competition and found that this stone is here, because there are only four or five sub-members, it is enough to deal with violent DFS. First, we regard the stone as a common obstacle, perform a full graph of DFS or BFs, find the available points, and then each time the DFS explores a new point in a new area, we can figure it out. #include
