Q$13$: For the castaway$\_$details DataFrame, there is a full$\_$name column and a short$\_$name column. It would be helpful for future analysis to have the contestants first and last name split into separate columns. First copy the castaway$\_$details DataFrame to a new DataFrame called Q$13$ so that we do not change the original DataFrame.

Create two new columns and add the contestant's first name to a new column called first$\_$name and their last name to a new column called last$\_$name. Add these columns to the Q$13$ DataFrame. Put the first$\_$name and last$\_$name columns between the full$\_$name and short$\_$name columns.

Note: Be careful as some players have last names with multiple spaces. For example, Lex van den Berghe. You should code Lex as his first name and van den Berghe as his last name.
