Required Files

• Ex13.9.scm: for Exercise 13.9

• Ex13.11.scm: for Exercise 13.11

• Ex13.13.scm: for Exercise 13.13

This lab also requires the following files, which must be in the same folder as your Scheme definitions:

• evaluate.scm: the arithmetic expression evaluator

• test-utilities.scm: the same test utilities file you've used before

You can get all the required files at once by downloading and then extracting this zipped code archive: stacks-queues-lab.zip.

After extracting, all files will be in the folder stacks-queues-lab. Leave all files in this folder so that it can be re-zipped for submission.
