--description--
m×n迷宫是m×n矩形网格,其中墙壁放置在网格单元之间,使得从左上角正方形到任何其他正方形恰好有一条路径。以下是9×12迷宫和15×20迷宫的示例:
设C(m,n)为不同m×n个迷宫的数量。可以通过来自另一个迷宫的旋转和反射形成的迷宫被认为是不同的。
可以证实C(1,1)= 1,C(2,2)= 4,C(3,4)= 2415,C(9,12)= 2.5720e46(科学计数法四舍五入为5显着位)。找到C(100,500)并用科学计数法将你的答案写成五位有效数字。
在给出答案时,使用小写e来分隔尾数和指数。例如,如果答案是1234567891011,则答案格式为1.2346e12。
