Problem Statement

You are given a collection of ABC blocks   (maybe like the ones you had when you were a kid).
There are twenty blocks with two letters on each block. A complete alphabet is guaranteed amongst all sides of the blocks. The sample collection of blocks:

Write a function that takes a string (word) and determines whether the word can be spelled with the given collection of blocks.

The rules are simple:

Let's start with the solution:
