Text Twist!

In Text Twist, players try to score points by forming words using the letters from a 6-letter scrambled word. They win the round if they can successfully unscramble the 6-letter word.

Create a function that takes in an array of already-guessed words, the unscrambled 6-letter word and returns the total number of points the player scored in a particular round using the following rubric:

1. 3-letter words are 1 pt
2. 4-letter words are 2 pts
3. 5-letter words are 3 pts
4. 6-letter words are 4 pts + 50 pt bonus (for unscrambling the word)

Remember that invalid words (words that cannot be formed from the 6-letter unscrambled words) count as 0 pts.

Examples

total_points(["cat", "create", "sat"], "caster") ➞ 2
# Since "create" is an invalid word.

total_points(["trance", "recant"], "recant") ➞ 108
# Since "trance" and "recant" score 54 pts each.

total_points(["dote", "dotes", "toes", "set", "dot", "dots", "sted"], "tossed") ➞ 13
# Since 2 + 3 + 2 + 1 + 1 + 2 + 2 = 13

Notes

• If a 6-letter word has multiple anagrams, count each 6-letter unscramble as an additional 54 pts. For example, if the word is arches, and the player guessed arches and chaser, add 108 pts for both words.
