Maze is a very interesting game, can exercise people's memory and thinking. Now, HK is trapped in a maze, please help him find a shortest path, can let him out of the maze.The maze uses a n*m matrix to describe the matrix with '. ' Represent the space can pass, use ' * ' stands for obstacles, use ' S ' to represent the starting point, use ' T ' to represent the exit. For example, a matrix below describes a 8*8 maze...... T.... *****.......*.*.***.*...

(x) $ is 0, the function value cannot be reduced. Therefore, you can use $ \ nabla f (x) $ as the termination condition. Because the first-order formula is used, if the step size is too large, such an approximation may be incorrect. In addition, the gradient descent method requires a long time to converge when the scale of the problem is large, so it is almost unavailable in reality.$ Newton method $ The Newton method can use Taylor's second-order extension to push: $ f (xK + dK) = f (xK) + \ n

. Conflict-related1. Conflict definition: assume that the address set of the hash table is 0 ~ (N-1), conflict means that the hash address obtained by the keyword is J (0 There is a record on the hash address obtained by the keyword, so it is called a conflict.2. handling conflicts: It is to tie the record of this keyword to another "null" hash address. That is, when the hash address conflict is processed, if the obtained hash address H1 still conflicts, the next address H2 is obtained. If H2 st
