apples Bessie can catch without walking the more than W times. Sample Input 9 |2121211 Sample Output 6 HintINPUT DETAILS: Seven apples fall-one from tree 2, then two in a row from tree 1, then two into a row from tree 2, then two to a row from Tree 1. Bessie is willing to walk from one of the other twice. OUTPUT DETAILS: Bessie can catch six apples by staying under tree 1 until the ' the ' I two have dropped, then moving to Tree 2 for the next T Wo, then returning 1 for the final two.

Description there is strings A and B with equal length. Both strings is made up of lower case letters. Now you have a powerful string painter. With the "help of the painter", you can change a segment of characters of a string of all other character you want. That's, after using the painter, the segment are made up for only one kind of character. Now the your task is to the change A to B using string painter. What ' s the minimum number of operations? Input input contains multiple cases. Each cas

The main topic: there is a lighting system need to use n kinds of lamps, each lamp voltage is V, power cost k, each bulb cost C, the number of lamps required is L. Note that the same voltage bulb only needs to share a corresponding power, and the low voltage bulb can be replaced by a high voltage bulb. In order to save cost, you will design a system to make the most inexpensive.Analysis: The first need to clear a light bulb or all, or do not change. If you change a part, the first power costs ar

problem B:the Largest clique Given a directed graph G, consider the following transformation. First, create a new graph T (g) to has the same vertex set as G. Create a directed edge between the vertices u and V in t ( G) If and only if there are a path between U and V in G so follows the directed edges only in the forward direction. This graph T (g) is often called the transitive closure of G. We define a clique in a directed graph as a set of vertices u such so for any of the vertices U and V

1090: [SCOI2003] string foldingTime Limit:10 Sec Memory limit:162 MB submit:1124 solved:734 [Submit][status][discuss] Description The definition of folding is as follows: 1. A string can be seen as its own folding. Recorded as Ss 2. X (S) is the folding of the string of X (x>1) s connected together. Remember as X (S) ssss ... s (x s). 3. If Aa ', Bb ', then Aba ' B ' For example, because 3 (a) = AAA, 2 (B) = BB, so 3 (a) C2 (b) AAACBB, and 2 (3 (a) C) 2 (b) AAACAAACBB gives a string to t
