I was just trying to come up with a small Scala function that would do the alphabet combination for me. Something like we have in Excel as the column headers:



The call would be:



Is there a much simpler way?

My solution only gives me from a to zz. I would like to rather have it a to abcdefghijklmnopqrstuvwxyz. I guess I might have to do a small tweak!

That seems like an odd stopping point...akin to saying "I want numbers from 0 to 123456789" why don't you want to go to zzzzzzzzzzzzzzzzzzzzzzzzzz?

hi Joe,

well, I tried to use as many functions as I could think of, but a decent classical while-loop
would be a lot easier...

But maybe someone can vastly improve on this code:

There are many ways to generate sequences. I would use haskell'ish style to do that:

This code creates an unbounded sequence of strings. You can adapt this code to generate sequences of limited length. In this case you would not need any laziness tricks.
