Recently, a program needs to be developed from C ++ to start a C # program and pass parameters. The specific method is: Call CreateProcess () on the C ++ side to start the C # side and pass relevant parameters. On the C # side, use main (string [] ARGs) to receive command line parameters. C ++Sending code: Int main (INT argc, char * argv []) { Char * filename = "C: \ csharp.exe "; Char * Params = "parameter 1 parameter 2 parameter 3"; // pass three parameters Process_information

converted to relatively small aa, bb, This formula uses n-n/p m-m/p to Solve the Problem recursively. Calculate c (aa, bb) and use the combination formula aa! /(Bb! * (Aa-bb )! ), Because Division exists here, bb is required! * (Aa-bb )! . The inverse of p in Euler's formula is pow_mod (a, P-2, p), that is, a ^ (P-2) % p; Therefore, the entire formula is converted to ret = (ret * fac [a] * pow_mod (fac [B] * fac [a-B] % p, P-2, p) % p; in this way, we can solve the problem recursively. In summa

The length of the longest non-descending path, and the difference in the maximum minimum value of the path is not greater than D.It is clear that the tree is divided, but how to maintain the answer after the partition.Assuming that the current center of gravity is g, the length of the non-descending path of G is recorded, as well as the maximum value, the length of the non-ascending path and the minimum value respectively.A map and two

Topic: Given a tree, so that the minimum cost of access to the K points in turn, each edge of the weight of 1.Thought: If can not go back, then this path is certainly the smallest, it depends on the given k, but how to determine the length of the walk, in fact, this is the diameter of the tree, also known as the longest simple path. After finding the diameter, just compare it with K to determine how many steps to take. Set the diameter of Maxx, if Maxx + 1== K words, it is not necessary to come
