Solution

#### Note:

This exercise has changed since this solution was written.

Given a word, compute the Scrabble score for that word.

## Letter Values

You'll need these:

``````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.

## Running the tests

To compile and run the tests, just run the following in your exercise directory:

``````\$ nim c -r scrabble_score_test.nim
``````

``````import sequtils, tables, strutils

const scoreTable = {
'A', 'E', 'I', 'O', 'U', 'L', 'N', 'R', 'S','T': 1,
