You are provided with four documents, numbered 1 to 4, each with a single sentence of text. Determine the identifier of the document which is the most similar to the first document, as computed according to the TF-IDF scores.

My name is Ankit,
Ankit name is very famous,
Ankit like his name
India has a lot of beautiful cities

Output the integer (which may be either 2 or 3 or 4), leaving no leading or trailing spaces.
