In the year 2163, wormholes were discovered. A wormhole is a subspace tunnel through space and time connecting two star systems. Wormholes have a few peculiar properties:
Wormholes are one-way only.The time it takes to travel through a wormhole is negligible.A wormhole has two end points, each situated in a star system.A st

Question: va-10192 vacation (LIS)
Evaluate the longest common substring of two strings.
Solution: recursive formula: S1 [I] = S2 [J], L [I] [J] = L [I-1] [J-1] + 1;
S1 [I]! = S2 [J], L [I] [J] = max (L [I-1] [J], L [I] [J-1]).
When I and j start with 0, L [I] [J] = 0;

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

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.

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.
