SG value of 0, will lose; X=3, you can take away 3-f{1,3} stones, the remaining {2,0}, mex{sg[2],sg[0]}={0,0}, so sg[3]=1; Can make the opponent SG 0; X=4, you can take away 4-f{1,3,4} stones, the remaining {3,1,0}, mex{sg[3],sg[1],sg[0]}={1,1,0}, so sg[4]=2;
X=5, you can take away 5-f{1,3,4} stones, the remaining {4,2,1}, mex{sg[4],sg[2],sg[1]}={2,0,1}, so sg[5]=3;

DescriptionThe funny stone game is coming. There is n piles of stones, numbered with 0, 1, 2, ..., n−1. BothPersons pick stones in turn. In every turn, each person selects three piles of stones numbered I, J, K(I Put one stone into pile j and pile K respectively. (Note:if j = k, it'll be the same as puttingStones into pile j). One would fail if he can ' t pick stones according to the rule.David is the player of the first picks stone

This information can be judged according to the global information.The above about how the communication between the contents of the server, is a personal guess, QQ in the end how to do, I am afraid only after one of us into the Tencent to know. Oh. However, one thing is for sure, in the entire server architecture, there should be a place that is dedicated to keeping a global list of logged-in players, only in order to ensure that players do not log on repeatedly and enter multiple rooms

There are a lot of online game blogs and papers, but some don't have a detailed proof, just a conclusion. Today, the author brings together some common game theory templates to introduce the decision of some single games in game theory and the common Nim templates and proofs.Note: The following games are based on the optimal

We define images of different animation frames through the sprite table, and then useCodeLoad each sprite (FRAME) into an animation and display the rendered Sprite on the screen. The first genie table above shows the genie running in different directions.

One talk about the search engine optimization strategy, basically can be divided into two kinds: one is to search engine as an imaginary enemy, try to conquer it, a kind of the enemy as a friend, as a strategic partner for optimization. Hangzhou SI billion Network Technology Co., Ltd. generally advocated by the search engine to make friends with the strategy, in fact, both strategies can become an effective

subclass.However, the irony is that if there are many sub-classes, there will inevitably be an alternative like Rubber Duck; it will be even worse if the sub-classes need to be constantly added, every time we raise the subclass behavior to the parent class, we will fear whether there will be an alternative in the future and cannot apply the logic already fixed in the parent class ......The following describes four different methods to solve this problem.
