Recursive Character Search and Destroy

I receive a string, and I want to remove any 'a', 'b' and 'c' characters, in a recursive way.

How do I do this in C and Java?

Thanks

Dumbass, recursion involves calling the same function FROM ITSELF. It doesn't matter if you call it one time or seven million, as long as the same function is listed in two descendant frames in the backtrace.
