In the attached file, it is a source code for a function, after you read this source code, you need to do the following things:

(1) Transfer this source code into a graph.

(2) For each node, mark what variables are defined, used, or both.

(3) List at least two testing techniques that you will use to test your transferred graph, and what kinds of test cases for each test techniques you will use.
