Vocabulary Index Mapping

Problem

Return a dictionary mapping each token in vocab to its integer index in the list.

Indices start at 0 and follow the order of vocab.

Hint

enumerate gives you both the index and the token.

case 1

in: [["a","b","c"]]

expected: {"a":0,"b":1,"c":2}

case 2

in: [["the","cat"]]

expected: {"the":0,"cat":1}

case 3

in: [[]]

expected: {}

case 4

in: [["one","two","three","four"]]

expected: {"one":0,"two":1,"three":2,"four":3}
