function based on the queue implementation, explained in detail hereFirst we set up a node queue q, we first add the starting point into the queue. From the beginning of the team of Q, use temp to get this team first, Q.pop (). The node that can go through temp will be added to the queue, and the end is determined.So knowing that the queue was empty, we went through all the possible ways.The code is as follows:1#include 2#include 3#include 4#include 5#include 6 using namespacestd;7 structnode8

coordinates of a dog are the same as those of D, the dog must take an even number of steps. That is to say, the coordinates x, y of a dog, and the remainder of 2 are their parity, and the remainder of Dxy and 2 are the parity of D. Two parity values: One Plus and two for the remainder, take the remainder and compare it with the remainder of the remaining time for two for the remainder. Parity pruning is a special trick in Data Structure search. Assume that the starting point is (sx, sy) and th

Label: gradient descent method, cut vector, method Vector Zookeeper First, it indicates that the gradient is perpendicular to the cut vector of the curve, that is, the gradient direction is the direction of the normal vector: Set the curve x = x (t), Y = Y (T), and z = z (T) to the surface u (x, y, z) = a curve on C (C is a constant, u (x, y, z) = C indicates the contour line). Because the curve is on the surface, x = x (t ), y = Y (t), Z = Z (t) satisfies the equation u (x, y, z) = C, that is,

Obviously for this problem, some points may need to be repeated (for example, there is a bomb-reset-equipment, maybe you need to go and come back), so mark each point should be recorded when the time to access the point, if the next time more can join the queue, Otherwise it doesn't make sense to join this point (because the total number of steps spent is more but the remaining time is not much).1#include 2#include 3#include 4#include 5 using namespacestd;6 7 Const intN =8;8 intMaze[n][n];9 intV
