Can anyone explain to me
- why the ** in "**20** lines"?
- why the $ in "length $n$"?
- which other path than 10-20-30-40-70-90 is possible in the sample program?
- what will say "the number of paths ... is the sequence 0,2,2,...?" Isn't the number dependent of a,b? Does 0 make sense?
Perhaps I'm the only one who doesn't understand this.
