Jailor problem door
hey you can reach 12 via 1,2,3,4,6,12th door so even number of times so it is closed , on other hand if take 9 you can reach it through 1,3,9 therefore odd no of times and it will be open. 13 will be reached only from 1 and 13 so closed.
i hope its clear @tejasddongare if yes don’t forget to hit like and mark the doubt resolved
