Before introducing the SG function and the SG theorem, let's introduce the winning and losing points.the concept of winning points and losing points:P-Point: Must lose the point, in other words, is who is in this position, then in both sides operation correct situation will defeat.N Point: Win point, in this case, both sides operate correctly under the circumstances to win.the nature of winning and losing p

Given a piece with a direction-free graph and a starting vertex, the two players alternately move the piece along a forward edge and cannot be judged negative by the mover. In fact, this game can be thought of as an abstract model of all impartial combinatorial games. In other words, any ICG can be abstracted into this "graph game" by taking each situation as a vertex and a forward edge to each situation and its sub-situation. Below we define the Sprague-grundy function on the vertex with the di

First defines the MEX (minimal excludant) operation, which is an operation exerted on a set, representing the smallest nonnegative integer that does not belong to this set. For example
Mex{0,1,2,4}=3, Mex{2,3,5}=0, mex{}=0.
For a given direction-free graph, the sprague-grundy function for each vertex of the graph is defined as follows: g (x) =mex{g (y) | Y is the successor of X, where G (x) is
SG[X].
For example: To take the stone problem, there are
a integer N, indicating the number of the heaps, the next line contains N integers s[0], s[1], .... , S[n-1], representing heaps with s[0], s[1], ..., s[n-1] objects respectively.

nearly 1000 of ICANN's authorized registrars. The domain registrar will check whether the domain name is available and establish a WHOIS record according to the information provided by the registrant. The registrant may also register the domain name through the distributor's affiliate. The organizations/individuals involved in the process of registering a domain name and the relationships between them are shown in the following illustration:
