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

OP here. It's for a comparative between iterative and recursive timings, memory consuption, etc... Which is all good, if it wasn't for the fact that I did...  one recursive function in my all life (factorial).
