### Problem Statement

The Simple Word Game is a game where a player tries to remember as many words as possible from a given dictionary. The score for each distinct word that the player remembers correctly is the square of the word's length.

You are given a String[] player, each element of which is a word remembered by the player. There may be duplicate words, but if the same word appears multiple times, it should only be counted once. You are given the dictionary in the String[] dictionary, each element of which is a single distinct word. Return the player's total score.

### Examples

0)

 `{ "apple", "orange", "strawberry" }` `{ "strawberry", "orange", "grapefruit", "watermelon" }`
`Returns: 136`
 The player has correctly remembered two words from the dictionary: "orange" (worth 6*6 = 36 points) and "strawberry" (worth 10*10 = 100 points). That gives a total score of 136 points.
1)

 `{ "apple" }` `{ "strawberry", "orange", "grapefruit", "watermelon" }`
`Returns: 0`
 The player has remembered just "apple" and it's not in the dictionary, so the score is 0.
2)

 `{ "orange", "orange" }` `{ "strawberry", "orange", "grapefruit", "watermelon" }`
`Returns: 36`
 The "orange" occurs twice in player, but should be counted just once towards the score.
3)

 ```{ "lidi", "o", "lidi", "gnbewjzb", "kten", "ebnelff", "gptsvqx", "rkauxq", "rkauxq", "kfkcdn"}``` ```{ "nava", "wk", "kfkcdn", "lidi", "gptsvqx", "ebnelff", "hgsppdezet", "ulf", "rkauxq", "wcicx"}```
`Returns: 186`
