## graphical sequences - graph theory

i have a question to do with graph theory and i have the complete answer but im not sure how to do some of the steps.

the question is: determine whether the sequence $s$ below is graphical and, if so, find a graph having $s$ as its degree sequence:

$s$: 5, 5, 4, 4, 3, 3, 3, 1, 0, 0
