Denary to binary
Go the other way: from a denary number to its binary digits.
Divide by 2 again and again. The remainder n % 2 is the next bit, and n // 2 is what is left to convert. The remainders come out right to left, so put each new bit at the front of the string. 0 needs its own answer, because the loop would never run.
Write to_binary(n) that returns the binary digits of a whole number n (0 or more) as a string, without using bin(). 11 gives "1011" and 0 gives "0".
