AnswersThere are five 10 monster As on the left of the road and 10 monster Bs on the right of the road, the road is with length 21 with a empty slot in the middle. Both A and B can jump over the other type or move forward to a empty slot but cannot move backward.

AA*BB --> AAB*B
AAB*B --> A*BAB

It seems that there is only one monster can get through the road. The number of steps is 2 * n(monsters) + 1.
The Question did asked how to let "them" get through.
Have I missed something important in the question?
