Assume that Edison has found himself in a square-shaped maze of NxN square cells which is surrounded by walls from the outside. In the maze, some of the cells are also walls. Edison can only move between two empty cells in four directions, north, south, west and east. In order to get out of the maze, he drafts a plan. He uses his left hand to lean on the wall and goes by following the wall. Here is the question, is Edison able to get out of the maze in at most 10,000 steps? If he can make it, output the path. By getting out of the maze, he only needs to be in the exit cell. If the starting cell is the same as the exit, Edison won"t need to move and can directly get out of the maze. Input The first line of the input gives the number of test cases, T. T test cases follow. Each test case starts with an integer N. N is the size of the maze. Th

随机学号发生器。如，如果用户选择0431班，使用序号为1，那么随机给出0431班中除了学号为1～10之外的其它所有学号中的n个学号；如果选择2，那么随机给出除了学号为10～20之间的其它n个学号；依次类推。-random generator, school. For example, if the user selects 0431 class, the use of a serial number. then randomly given 0,431 school classes, in addition to a 10-all other outside the school, the school n; If you choose two, then were given school, in addition to between 10 ~ 20 other school n; followed by analogy.
