Scrabble

Today's challenge is inspired by the board game Scrabble. Given a set of 7 letter tiles and a word, determine whether you can make the given word using the given tiles.

Write a function scrabble(inputString, outputString) that takes two arguments: (1) a string of letters with which to make words, and (ii) the word which we want to form. It should return true if outputString can be formed from inputString, and false if otherwise.

Examples:

scrabble("ladilmy", "daily") -> true
scrabble("eerriin", "eerie") -> false
scrabble("orrpgma", "program") -> true
scrabble("orppgma", "program") -> false

Optional Bonus 1

Handle blank tiles (represented by "?"). These are "wild card" tiles that can stand in for any single letter.

scrabble("pizza??", "pizzazz") -> true
scrabble("piizza?", "pizzazz") -> false
scrabble("a??????", "program") -> true
scrabble("b??????", "program") -> false

Optional Bonus 2

Given a set of up to 20 letter tiles, determine the longest word from the enable1 English word list that can be formed using the tiles.

longest("dcthoyueorza") ->  "coauthored"
longest("uruqrnytrois") -> "turquois"
longest("rryqeiaegicgeo??") -> "greengrocery"
longest("udosjanyuiuebr??") -> "subordinately"
longest("vaakojeaietg????????") -> "ovolactovegetarian"

(For all of these examples, there is a unique longest word from the list. In the case of a tie, any word that's tied for the longest is a valid output.)

Optional Bonus 3

Consider the case where every tile you use is worth a certain number of points, given on the Wikipedia page for Scrabble. E.g. a is worth 1 point, b is worth 3 points, etc. For the purpose of this problem, if you use a blank tile to form a word, it counts as 0 points. For instance, spelling "program" from "progaaf????" gets you 8 points, because you have to use blanks for the m and one of the rs, spelling prog?a?. This scores 3 + 1 + 1 + 2 + 1 = 8 points, for the p, r, o, g, and a, respectively. Given a set of up to 20 tiles, determine the highest-scoring word from the word list that can be formed using the tiles.

highest("dcthoyueorza") ->  "zydeco"
highest("uruqrnytrois") -> "squinty"
highest("rryqeiaegicgeo??") -> "reacquiring"
highest("udosjanyuiuebr??") -> "jaybirds"
highest("vaakojeaietg????????") -> "straightjacketed"
