Solution

#### Note:

This solution was written on an old version of Exercism. The tests below might not correspond to the solution code, and the exercise may have changed since this code 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.
