. 4. Then the support of the son made a line Eat Chess strategy: 1. Give priority to eating the other person trying to connect. 2. Secondary to eat each other's fortress 3. Third, eat each other to stop the connection you're completing. 4. And finally eat the child outside the corner. Flying move: There are 3 of them left to run around. It's dangerous to let each other run when you're less than 8, a

Planning) similar methods. Note: If the hacker uses the method of profiteering cracking, the time complexity is O (n ^ 2), and the time limit is exceeded.

Topic: Given a tree, each point has a point right, several times to change the point of the right, multiple queries with the right center of gravity to all points of the sum of the right distanceNo regrets in this life into the east, the afterlife is willing to birth fantasy TownshipFirst we consider how to calculate the sum of the weighted distances of a point to all points and support the modificationIt would be nice to divide it with a dynamic tree

In the current version of redis,Sds_max_preallocIs1024*1024, That is, when the size is smaller1 MBWhen the append operation is performed,SdsmakeroomforAllocate more space than the required size. When the string size is greater1 MB, ThenSdsmakeroomforThey are allocated more1 MB. ExecutedAppendThe command string carries additional pre-allocated space, which will not be released unless the key corresponding to the string is deleted, or after redis is disabled, no pre-allocated space will be alloca

• When solving problems by division, the number of sub-problems is often the exponential function of the problem size, so the time consumption is too large. • The idea of dynamic planning is that if each sub-problem is not independent, the number of sub-problems is only polynomial magnitude, and we can save the answers to the sub-problems that have been solved, and then find the answers when needed, so that a large number of repeated calculations can

Q1:Number games:Two persons (A, B) a row of board games lined with n integers, the game starts with a, each person has the following actions:(1) Take the right or left-hand piece of the board and erase the removed number from the board.(2) When there are more than two numbers left in the chessboard, you can erase the two numbers on the right or left of the chessboard.When all the numbers on the board disappear, the game ends, who takes the pieces representing the sum of the larger number of peop

Data fragmentation allows data storage to be controlled at the table level. "Table Fragmentation" is a feature of the Informix database. Users can group records or indexes in a table and store them in different locations so that data can be stored on multiple disks, thereby reducing competition for disk I/O. The scheme of data slicing and a set of dbspace stored in the fragment data constitute the "slicing strategy". There are two basic types of data
