Link to the question: Ultraviolet A 716-commedia dell 'arte
Given a three-dimensional octal digital, 0 represents an empty position and asks if it can be sorted back.
Solution: for the case where N is an odd number, consider the reverse logarithm of the three-dimensional octal digital to consider the case where the State goes down, except 0, and the even number, consider transferring the position of 0 to (n, the reverse logarithm of the corresponding

Question: Given A Three-Dimensional n digital game, it is required to change to order, and the last position is space. Can it be changed successfully?
Idea: The same as the two-dimensional determination method, because the Z axis moves, it is equal to switching N ^ 2-1 times, the Y axis moves

Use just uses a namespace,
But to invoke the class, you have to load the class file, or load it automatically.
Even if one of the classes is introduced, if there is no automatic loading mechanism, it will be an error.
Several usages of use
