than the corresponding base dimensions of the lower block because There have to is some space for the monkey to step on. This is meant, for example, which blocks oriented to has equal-sized bases couldn ' t be stacked.Your job is to write a program this determines the height of the tallest tower the monkey can build with a given set of BL Ocks.Inputthe input file would contain one or more test cases. The first line of all test case contains an integer n,Representing the number of different bloc

have two DNA sequences S1 and S2, and the maximum match for S1 and S2 is the length of the longest common sub-sequence of S1 and S2. [Task] Write a program:? Read two equal-length DNA sequences from the input file; Calculate their maximum match;? Print the results you get from the output file. The first line in the input file has an integer n, indicating that some species on the planet use n different bases, and they are numbered 1 later ... An integer of N. There are two lines below, each of w

The main effect of the topic: There are n items, each item has a volume and value of two attributes, a thief with a size of V backpack, to steal these things, ask thieves can steal the value of the number k? Ideas: This problem and typical 01 knapsack to seek the best solution is different, is to ask K large solution, so, the most intuitive idea is to add one dimension on the base of 01 backpack, to save the number of the first k size, and then in the recursion, according to the previous stat

illuminate the number of edges as little as possible. You can become the minimum value of the ball m*a+b, a for the number of lights placed, b for the number of sides by a lamp F[U][1] represents the minimum value of the entire subtree when a U-point light is placed F[u][0] represents the minimum value of the entire subtree when the U-point does not place the lamp if u put, then you can choose to put the sub node, you can also do not put, select the smaller values. If you choose not to take

The main effect of the topic A stick with a long l, with n "Tangent points" on it, and the position of each point is c[i] We have to cut every point in a certain order, and then it turns into a n+1 segment. Each time you cut, there is a cost, such as 10, "tangent" to 2, then the cut will become two paragraphs 2, 8, then the cost of 2+8=10 If you have more than one tangent, you will get different costs in different order. How much is the minimum cost? Ideas Note To add a c[n] = l F (I, j)

, then we can determine x = f (i-1, j-1) + 1. If the ball is not broken in the X layer, then we only spend the cost of one time, and I have the ball, the j-1 time can be used, then the number of layers can be determined F (i, j-1) So, get the recursive type and push the highest level of certainty: F (i, j) = f (i-1, j-1) + 1 + f (i, j-1); Code /**===================================================== * is a solution for ACM/ICPC problem * * @source: UVA -10934 Dropping water balloons * @desc

Meaning to a N-node tree, the node number is 1~n, the root node is 1, and each node has a weight value. Starting from the root node, go no more than k step, ask the maximum number of weights can be obtained? Ideas Because it's a bit like uva-1407 caves, I didn't think about AC for a long time, but because of the initialization problem WA twice F (i, J, 0): Represents the subtree I, walks the J times, and ultimately does not have to return to the I point to obtain the maximum total weight F (I, J

Meaning An N-node tree that, when removed from a node, becomes a forest. Each tree in this forest has a number of nodes, where the maximum number of nodes is set to Max. Ask how much is max when you delete a node? Ideas Exactly the same as poj-3107 Godfather! Don't want to spit the groove ... In fact, did not want to send this article, but found today is the last day of August, but also one of the 80 published. So.. It's a wicked water. Code /**===========================================

"cf908e" New year and Entity enumerationTest Instructions : Given $m=2^m-1$, we call a set S to be good when and only if it satisfies: 1.$\forall a\in s,a \mathrm{xor} M \in s$,2.$\forall a,b\in s,a \mathrm{and } b \in s$,3.\forall a\in s,a\le M.Now given the set T, ask how many good sets of s, satisfying t is a subset of S.m The puzzle: Obviously with and take reverse after, we can also achieve OR and XOR. What can we do with the number in T after we have given t? It is easy to find that if bit

We know that when the x coordinates of the points in the slope optimization dp are not monotonous, the splay is needed to maintain the convex hull, but the code is larger and easier to write and hang.We also have a magical way of doing things: CDQ Divide and conquer.First, the N states are arranged into a sequence. Consider a divide-and-conquer process solve (l,r), each divided into [l,mid],[mid+1,r] two parts.Obviously for Fi only and 1~i-1, so we So
