Scrabble Score

Instructions

Your task is to compute a word's Scrabble score by summing the values of its letters.

The letters are valued as follows:

For example, the word "cabbage" is worth 14 points:

• 3 points for C
• 1 point for A
• 3 points for B
• 3 points for B
• 1 point for A
• 2 points for G
• 1 point for E

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 scrabble-score.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 scrabble-score input-list). To learn more about apply see The Scheme Programming Language -- Chapter 5
