# Scrabble Score
|
|
|
|
Given a word, compute the scrabble score for that word.
|
|
|
|
## Letter Values
|
|
|
|
You'll need these:
|
|
|
|
```text
|
|
Letter Value
|
|
A, E, I, O, U, L, N, R, S, T 1
|
|
D, G 2
|
|
B, C, M, P 3
|
|
F, H, V, W, Y 4
|
|
K 5
|
|
J, X 8
|
|
Q, Z 10
|
|
```
|
|
|
|
## Examples
|
|
|
|
"cabbage" should be scored as worth 14 points:
|
|
|
|
- 3 points for C
|
|
- 1 point for A, twice
|
|
- 3 points for B, twice
|
|
- 2 points for G
|
|
- 1 point for E
|
|
|
|
And to total:
|
|
|
|
- `3 + 2*1 + 2*3 + 2 + 1`
|
|
- = `3 + 2 + 6 + 3`
|
|
- = `5 + 9`
|
|
- = 14
|
|
|
|
## Extensions
|
|
|
|
- You can play a double or a triple letter.
|
|
- You can play a double or a triple word.
|
|
|
|
|
|
Run the tests with:
|
|
|
|
```bash
|
|
bats scrabble_score_test.sh
|
|
```
|
|
|
|
After the first test(s) pass, continue by commenting out or removing the
|
|
`[[ $BATS_RUN_SKIPPED == true ]] || skip`
|
|
annotations prepending other tests.
|
|
|
|
To run all tests, including the ones with `skip` annotations, run:
|
|
|
|
```bash
|
|
BATS_RUN_SKIPPED=true bats scrabble_score_test.sh
|
|
```

## External utilities
|
|
`Bash` is a language to write "scripts" -- programs that can call
|
|
external tools, such as
|
|
[`sed`](https://www.gnu.org/software/sed/),
|
|
[`awk`](https://www.gnu.org/software/gawk/),
|
|
[`date`](https://www.gnu.org/software/coreutils/manual/html_node/date-invocation.html)
|
|
and even programs written in other programming languages,
|
|
like [`Python`](https://www.python.org/).
|
|
This track does not restrict the usage of these utilities, and as long
|
|
as your solution is portable between systems and does not require
|
|
installation of third party applications, feel free to use them to solve
|
|
the exercise.
|
|
|
|
For an extra challenge, if you would like to have a better understanding
|
|
of the language, try to re-implement the solution in pure `Bash`,
|
|
without using any external tools. Note that there are some types of
|
|
problems that bash cannot solve, such as performing floating point
|
|
arithmetic and manipulating dates: for those, you must call out to an
|
|
external tool.
|
|
|
|
## Submitting Incomplete Solutions
|
|
It's possible to submit an incomplete solution so you can see how others
|
|
have completed the exercise.
