Answer 1

if i take your code and give an input of:

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14
the result is:

zero one two three four five six seven eight nine onezero oneone onetwo onethree onefour

The reason is that you take the input as a string and iterate over it. So you pick each single character (digit)to check insted of doing check with the numbers.
The input should be converted to a list, which you should iterate over.
