Bro it will fail this test case .
Your code’s output here will be 5 which is wrong . The correct answer is 3.
According to your code ,
You will start at 3rd floor go to 2nd floor again come to 3rd floor then go to 4th floor then reach 5th floor .
Time elapsed = 5 minutes
Right order ,
You will start at 3rd floor goto 4th floor then reach 5th floor .
Time elapsed = 3 minutes
Hope you understood your mistake
