    Read them into a string, or character by character.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Let's say the user entered 52314.

    If you wanted to work right to left, you could take the remainder after dividing by 10 and that would give you 4. Doing it again would give you 1, then 3, then 2 then 5, and you would then stop because your number remaining would be 0.

    If you wanted to work left to right, you could determine, in a loop, the power of 10 the number adheres to. In this case, it would be 10,000. Dividing by 10,000 would give you 5. Then, subtract out 50,000, reduce the power of 10 by one to give yourself 1,000 and divide 2,314 by that. That would give you 2. And, so on.
