Not to be the grammar police here, but it was difficult to determine the wording on this part:

"You will be given two inputs a word and an array with words."

Please consider using:

"You will be given two inputs: 1) a word, and 2) an array with words" or something similar.

The original wording is difficult to read, and it took me a few attempts (as a very new learner) to figure out what it was stating.
