Before going on this trip, you’ve gathered some information about the Lord Escher's quirks. One of them was a very unusual numbering of doors - he numbered them according to how the numbers go in the alphabetical order. For example, if there were five doors positioned from left to right, they were numbered as: five, four, one, three, two (instead of a completely logical numeration - 1, 2, 3, 4, 5). Thus, the very last door was actually the leftmost, not the very right one, as it might be assumed. Your task is to find the very last door.
As input your function will receive an integer - the total number of doors in the current room. You will need to sort the door numbers in the order in which these numbers, expressed in words, go in the alphabetical order. And then return the position number of the last door (the door with the highest number). The count starts from the 1st position (not from the 0th). The maximum number of doors is 1000. The numbers after 100 are written in the format like - 'one hundred twenty nine'.
Input: the door number.
Output: the 'right' door number.
secret_room(5) == 1, #five, four, one, three, two secret_room(3) == 2, #one, three, two secret_room(1000) == 551
How it is used: For the work with numbers in their alphabetical representation.
2 <= amount of the doors <= 1000
