Title DescriptionA maze of n * m lattices, starting at (1, 1), the end point is (N, m), each can go to the upper and lower left and right four directions any step, and some of the lattice is unable to move around, from the beginning to the end of each lattice at most once the number of walk.Enter the first line an integer t indicates that there is a T group of test data. (T For each set of test data:The first row of two integers n, m, indicates that the maze has n * m lattice. (1 Any two sets of

The i -th Line of the next n Lines contains one, string of length m , which represents i -th row of the maze.Outputfor each testcase, print the answer in binary system. Eliminate all the precedin

Problem DescriptionIn ann∗m Maze, the Right-bottom corner is the exit (position(n,m) is the exit). In every position of this maze, there is either a0or a1Written on it.An explorer gets the lost in this grid. His position are(1,1) , and he wants to go to the exit. Since to arrive at the exit was easy for him, he wants to does something more difficult. At first, he'll write down the number on position (1,1). Every time, he could make a move to one adjacent position (both positions is adjace

Test instructions: In a matrix of only 0 and 1, from the upper left corner to the lower right corner, each can go to four directions, each path is a binary number, the smallest binary number in all paths.Solution: First BFS to go from the starting point to the nearest 0 to the end, then from this point only down or to the right to get the least number of binary numbers, and then greedy to think, if after or under 0 must go 0, no 0 1 are looked over, to the previous search of 0 to do the starting

The requirement for moving from point A to Point B is: the shortest path from point A to the end point> the shortest path from point B to the end point.Thought: at this moment, we need to first find the shortest path from all points to the end point, then we can start from the end point and find the shortest path. Then, we use the memory-based search to find the points that match the meaning of the question.AC code:

Because there is not much to use, prototype mode is typically used to create a class of objects multiple times, to get multiple objects of this class, and to do the appropriate operation, the general practice is to come out multiple times, but the prototype mode is the first time to copy the object created, and then multiple copies
