# Instructions
2+
3+
Your task is to compute a word's Scrabble score by summing the values of its letters.
4+
5+
The letters are valued as follows:
6+
7+
| Letter | Value |
8+
| ---------------------------- | ----- |
9+
| A, E, I, O, U, L, N, R, S, T | 1 |
10+
| D, G | 2 |
11+
| B, C, M, P | 3 |
12+
| F, H, V, W, Y | 4 |
13+
| K | 5 |
14+
| J, X | 8 |
15+
| Q, Z | 10 |
16+
17+
For example, the word "cabbage" is worth 14 points:
18+
19+
- 3 points for C
20+
- 1 point for A
21+
- 3 points for B
22+
- 3 points for B
23+
- 1 point for A
24+
- 2 points for G
25+
- 1 point for E
