Programming with C++

1) Explain the steps to deleting a node from the middle of a singly-linked list. No need to code, just pseudo-code or bullet points will work.

2) Explain the steps to deleting a node from the end of a doubly-linked list (either head or tail). No need to code, just pseudo-code or bullet points will work.

3) Why would a tree be more useful than a list? Give an example of a circumstance in which a tree is better in some way.
