Given these instructions for creating a flowchart for code:

$-$Use flowchart shapes defined as $-$ ovals for start and end, diamonds for boolean statements, and rectangles for statements.$$ You can use a slanted rectangle, or non slanted rectangle, for you input and output.

$-$The flowchart represent the algorithm as it is given in the code.$$ Do not modify the code.

How would I create the flowchart for the screenshot of code included? It would be very helpful if you could include a bit of thought process behind each shape you add since I$\text{'}$m very confused on how to do this.

Thank you very much for any help!
