I am working on a homework problem for Dijkstra's shortest paths algorithm and part of the requirement is to use a partially ordered tree instead of a priority queue. This is the first time looking at Dijkstra's algorithm and i am not sure how the priority queue would be used to begin with so using a partially ordered tree instead has me completely lost. I am looking for an explanation of how the priority queue would be used and how a partially ordered tree can replace it. Thanks.

What you want to use is a binary heap. The root element of a binary heap is the smallest element in the collection, which will be removed on pop() operations.
