For this assignment, set the DrScheme Language
to How to Design Programs: Beginning Student with List Abbreviations.
Your assignment is correct only if you
use the correct language level.

• Read Recipe Guidelines for "Chapter 2 onwards". Correctness of
  your code is assumed. Most of the grade is on following the recipe.

• Book problems: 8.3.1, 8.3.2, 9.3.3, 9.5.2, 9.5.7, 10.1.5, 10.1.7

• NB: Be sure to do all the assigned parts of each problem. In the
  book, each problem ends with a block icon. Online, each problem ends
  with a hand icon.

• Read chapter 8 very carefully before doing the problems from
  that chapter. This chaper is not padded with lots of wordy
  examples. In writing hand evaluations for problems 8.3.1 and 8.3.2,
  follow the same format as the examples in Section 8.3, which is shown
  in more detail in the hand-evaluation examples posted on the course wiki.

• In writing programs, follow the recipe carefully and in the
  correct order. This means, write down the purpose, contract, develop
  examples (hand in 5), write the actual function, and include
  illustrative test cases for the function (using at least the examples
  you developed ahead of time). The examples should illustrate the
  output you expect, and the test cases should produce the actual output
  (they should not be commented). Add notes at the end of each problem
  to indicate wether the examples actually helped you in catching bugs.
