How to open a fragment from a notification?

Write a code fragment to illustrate 5 of the nodes of a doubly linked list?

Diagram here: http://img837.imageshack.us/img837/3144/csftl.png 1. Write a code fragment to move/reposition the URhere reference in Diagram #1 left by 2 nodes. 2. Write a code fragment to move/reposition the URhere reference in Diagram #1 to point at the head node (not shown). 3. Write a code fragment to swap the content of node referenced by URhere with the content at the head node (not shown) in Diagram #1. 4. Write a code fragment to remove the node referenced by URhere in Diagram #1. 5. Write a code fragment to add a new node (with string “last”) on the right side of the node referenced by URhere. I tried teaching myself online about Data Structures, but none of it goes into detail what each line of codes do. Any help is appreciated! Thank you.
