This is what I'm doing:

I am practicing a problem in "Cracking the Coding Interview". The problem is to remove duplicates in a linked list without the use of a buffer. I interpreted this as not using a list or any large data structure such as a hash to store unique nodes.
My algorithm is inefficient I think. It iterates an anchor across the ... | stackexchange/codereview |
