About the ISBN parser: What is it supposed to do if more than 10 digits appear in the input? Say "invalid ISBN"? or regard only the first 10 digits and proceed as normal?

u should reset switcher to zero at the beginning of the while loop, else it will print wrong BGC combinations.

well I added a a<0 or b<0 check to my functions, but still it's saying wrong answer

Hi,

following problem: what does pile a over b do if b is in the stack above a?

Example: (from the problem example data)
after the move instructions, I have:

0: 0
1: 1 9 8 7 6
2: 2
3: 3
4: 4
5: 5
6: 6
7:
8:
9:

The next command is "pile 8 over 6", but 6 is in the stack containing 8. So how is the ...
