立方数码问题（8数码问题的三维拓展）

使用C/C++实现4个算法，即，使用启发函数h1(n)的A*算法：Astar_h1.cpp，使用启发函数h2(n)的A*算法:Astar_h2.cpp，使用启发函数h1(n)的IDA*算法:IDAstar_h1.cpp，使用启发函数h2(n)的IDA*算法:IDAstar_h2.cpp。输出文件名与算法对应。以h1为启发函数的A*算法输出到output_Ah1.txt；以h2为启发函数的A*算法输出到output_Ah2.txt；以h1为启发函数的IDA*算法输出到output_IDAh1.txt；以h2为启发函数的IDA*算法输出到output_IDAh2.txt。-Cube puzzle problem (three-dimensional expansion of 8 digital issues) using C/C++ implement four algorithms that use heuristic function h1 (n) of the A* algorithm: Astar_h1.cpp, using heuristic function h2 (n) of the A* algorithm: Astar_h2.cpp, using heuristic function h1 (n) of the IDA* algorithm: IDAstar_h1.cpp, using heuristic function h2 (n) of the IDA* algorithm: IDAstar_h2.cpp. Corresponding to the output file name and algorithms. In the heuristic function h1 A* algorithm outputs to output_Ah1.txt　h2 as heuristic function with A* algorithm outputs to output_Ah2.txt　h1 as heuristic function to IDA* algorithm outputs to output_IDAh1.txt　with h2 as heuristic function The IDA* algorithm outputs to output_IDAh2.txt.
