Hello everyone , i'm new to programming, and get often stuck when making some programming exercises, but I usually managed to just google the problem.

This time I'm stuck with this assignment from CS50 Harvard course called "credit".

This could be done by reading characters and ending at a new line, but this way is much simpler.

The code requires input be separated by spaces and ended with a number greater than 10 to exit the reading loop.

Numbers larger than 100 are not recognized by the interpreter in literal form and must instead be entered as "native" numbers (i.e. Since internally, a native number is just a sequence of the digits in reverse order with an end digit marker, converting the number into a reversed list of digits mainly involves removing this terminator, so that we can immediately treat the digits as number elements.
