The qoncept problem
You are in a building with 345 rooms. In each room you will meet a highly motivated potential employee. You would actually want to hire every single one of them, but unfortunately this is not possible. Your boss gives you the following task: Here is the master key for the rooms, walk through the building 345 times. At the first walk-through use the key in every room, on the second walk-through in every second room, …, on the nth walk-through in every nth room. The locks always open and close alternately. In the beginning all locks were closed. How many highly motivated individuals find an open door after the 345th walk-through?
