Alien Dictionary Evaluation

Perform division operations in an alien language environment, similar to the Evaluate Division problem. Given several division relationships and queries, return the result of each query. Each relationship is of the form a/b = value, where a and b are different strings, and value is a float. Return the result of query xy/z, or -1 if it cannot be determined. Example Input [('a', 'b'), ('b', 'c')], [2.0, 3.0], [('a', 'c'), ('b', 'a'), ('a', 'e'), ('a', 'a')]
