Match all capturing groups

In this exercise, you will work with a text file named top_10 which stores movie names and their rank. In this multi-line text, \\n is used to start a new line. You will use the str_split() function to split the text file into multiple lines.

The newly created one-rowed matrix top_10_lines then contains ten lines with the same pattern: The rank of the movie, followed by a dot and a space and the movie title itself. The function str_match() and two capturing groups () will make it possible to extract these two pieces of information from plain text into a tabular form.

Use the str_split() function to split the text into its lines, outputting a character matrix by enabling simplify.
Familiarize yourself with the structure of a line. It contains the rank and the title of a movie.
Extract the rank and the title of a movie by using capturing groups in the str_match() function.
