Bob

Instructions

Your task is to determine what Bob will reply to someone when they say something to him or ask him a question.

Bob only ever answers one of five things:

• "Sure." This is his response if you ask him a question, such as "How are you?" The convention used for questions is that it ends with a question mark.
• "Whoa, chill out!" This is his answer if you YELL AT HIM. The convention used for yelling is ALL CAPITAL LETTERS.
• "Calm down, I know what I'm doing!" This is what he says if you yell a question at him.
• "Fine. Be that way!" This is how he responds to silence. The convention used for silence is nothing, or various combinations of whitespace characters.
• "Whatever." This is what he answers to anything else.

Track Specific Notes

See if you can clearly separate responsibilities in your code.

Running and testing your solutions

From the command line

Simply type make chez if you're using ChezScheme or make guile if you're using GNU Guile. Sometimes the name for the scheme binary on your system will differ from the defaults. When this is the case, you'll need to tell make by running make chez chez=your-chez-binary or make guile guile=your-guile-binary.

From a REPL

• Enter (load "test.scm") at the repl prompt.
• Develop your solution in bob.scm reloading as you go.
• Run (test) to check your solution.

Failed Test Cases

If some of the test cases fail, you should see the failing input and the expected output. The failing input is presented as a list because the tests call your solution by (apply bob input-list). To learn more about apply see The Scheme Programming Language -- Chapter 5
