Binary tree deletion code
WebNov 5, 2016 · I think what I like most about this is that it's clear to other people that head may indeed change. I like to do this for any functions that can cause head to change (in other situations, eg. linked lists, queues, etc, too). That way, it seems far less likely that problems of dangling pointers will crop up in group projects and commercial environments. WebYou never actually delete anything. There are two ways to do this.
