The question requires that all valid locations of "" (a) and "" (B) be output, and only one byte storage variable can be used; Solution 1: 1 #includeView code There are nine methods for a and B, So I = 81, for an integer I = I/9*9 + I % 9; I % 9 with I/9 change round, it is equivalent to a nested loop; an I is used to represent the changes of two values; Of course, you can also use this method to implement multiple nesting; Solution 2: 1 #includeView code Refer to related bit operations The b

Http://acm.hdu.edu.cn/showproblem.php? PID = 1, 4405 There are n + 1 points, 0 ~ N. A person is standing at X now. If Flight lines exists at X, he can fly to the corresponding point without rolling the dice. Otherwise, he will move forward to the number on the dice. Asked him the average number of times he needed to throw a dice from. For the same question type, DP [N] is known to be 0, and then the inverse is performed based on the probability that the current point can reach the next point.

Question LinkGiven a directed acyclic graph (DAG) with some flags on it, the flag can overlap. Two people can take turns and move a flag from one position to another, if the device cannot be moved, enter and ask if the player must win. This question can regard each flag as a separate game. Then, the SG values of all these flags are the XOR and SG values of these flags, which can be memorized for searching DFS, the SG value can be used for brute force calculation. #includeView code [Original blo

Generate valid methods Reprinted by the author: By: 88250 Blog: http:/blog.csdn.net/dl88250 MSN Gmail QQ: DL88250@gmail.com Method generation is to generate all valid methods, so that computer players can choose the best method in these methods, and finally come out of this. To generate all methods, you can only use the exhaustive method. About 45 Chinese chess methods can be selected at each step. The following code is used: /** * Genera

Cocos2d-X development of Chinese chess "seven" new board function implementation, cocos2d-x "seven" In the previous section, I introduced the implementation of the starting function. In this blog, I will introduce the implementation of the new functions. First, let's take a look. We can see the Implementation ideas of the new Bureau through the observed implementation results. 1.
