 * A Wily Puzzle
 * ''An unscrupulous advertiser offered a hundred dollars for a correct solution to this puzzle:


 * A life prisoner appealed to the king for pardon.
 * Not being ready to favour the appeal, the king proposed a pardon on condition that the prisoner should start at cell $A$
 * and go in and out of each cell of the prison, coming back to the cell $A$ without going into any cell twice.

 * Either the advertiser had no answer, and knew he had none,
 * or he was prepared to fall back on some trick or quibble.


 * What is the best answer the reader can devise that may be held to comply with the advertiser's conditions as given?
