What's the real floor?

Task Overview

Americans are odd people: in their buildings, the first floor is actually the ground floor and there is no 13th floor ('cause of superstition).

Write a function that given an American floor (passed as an integer) returns the real floor. Moreover, your function should work for basement floors too: just return the same value as the passed one.

Usage Examples :

get_real_floor(1) == 0
get_real_floor(0) == 0 # Special case to please Europeans
get_real_floor(5) == 4
get_real_floor(15) == 13
get_real_floor(-3) == -3

Given Code

def get_real_floor(n):
    # code here

---

Solution 1

def get_real_floor(n):
    if n <= 0:
        return n
    elif n >= 13:
        return n-2
    else:
        return n - 1

---

Solution 2

def get_real_floor(n):
    return n if n < 1 else n - 1 if n < 13 else n - 2
