It is also a minimal spanning tree problem. Special Judge. The answer is not unique. So the sample looks wrong... It is also a sad G ++ AC. Submit C ++ and then WA...

This afternoon looked at the KM algorithm, because the big guy's blog introduction is very brief, so he has not been clear some of the details of the problem, good to come back to a better csdn column, the introduction of more detailed, their own figure to understand a lot of confusion, the best matching two-point map.Summarize the algorithm:Idea: km algorithm is to change the number of feasible points, and constantly increase the amount of viable edges in the graph until there is a perfect matc

key as the key value for interprocess communication of a method, such as how to Shmget shared memory. The function prototype for Shmget is int Shmget (key_t, size_t, flag); After the creation is successful, the descriptor for the shared memory is returned. The key_t used in Shmget is generated by the Ftok way. Instance: #include #include #include #include #include #define SIZE 1024 extern int errno; int main (){int shmid;Char *shmptr; Create shared memoryif ((Shmid = Shmget (Ipc_private, SIZE,

wise use of the mutable keyword can improve the code quality, because it allows you to hide implementation details to users without using uncertain things, such as const_cast The Chinese meaning of mutalbe is "variable, easy to change", which is the opposite of constant (const in both C ++. In C ++, mutable is also set to break through the const restrictions. Variables modified by mutable will always be in a mutable state, even in a const function. We know that if the member function of t
