a Spy named James need to go out of a Security Tower.
this tower was composed of columns and doors , and James has only a Control-Panel with him , this panel allow him to open some doors.
But when he open a door , another can be blocked.
SO , we have :
- some columns blocked , so James can't go out.
- each column is consisted of doors
Good thing : 1 door open -> column open
Bad thing : we need every columns open.
the goal is to have the solution of the Control-Panel to open each columns.
Work done with Christophe Forycki.
