Score the Spelling Bee

Bee rules: every correct word scores 2 points, and completing each run of THREE correct in a row earns a +5 streak bonus (a run of six = two bonuses!). 🐝

You get the speller's answers and the key (matching lists). Print the final score.

Example:

Input: answers = ["cat", "dog", "fox", "owl"], key = ["cat", "dog", "fox", "elk"] Output: 11

cat, dog, fox are correct — 3 in a row, earning a +5 streak bonus on top of 3 × 2 = 6 points. Then owl is wrong. Total: 6 + 5 = 11.
