Ok... that's there... but wat about any odd no. or even no... the no. of factors are even for them...
so when the door was initially closed, so at the end od (even) iterations it will be closed only na....

there was a question i need an answer for:
the question starts like thsi :
Along a long corridor, there are 100 doors. The doors can be in either of two states: closed or open.
initially they are in closed state.
Person no. 1 changes the state of all doors that are a multiple of 1 i.e. basically all doors.
Person no. 2 changes the state of all doors that are a multiple of 2 i.e. even nos and so on till the person no. 100 changes the state of the door that is multiple of 100.
Now how many doors are closed?
