My slides say that

A recurssive call should always be on a smaller data structure than the current one

There must be a non recurssive option if the data structure is too small

You need a wrapper method to make the recurssive method accessible

Just reading this from the slides makes no sence, especially seeing as it was a topic from before christmas!

Could anyone try and clear up what it means please?

Thank you
