$"$a$)$ The 'title' column should be treated as text and not a categorical variable $($it$\text{'}$s the title of the page on which the car is sold$).$ Use the left$-$arrow symbol and redefine the values in the "title" current values to convert it into text. Then, run 'nchar' $($which counts up the number of characters$)$ on the $37$ th$,787$ th$,$ and $995$th cars' titles $($hint: in the square brackets put in the vector containing these $3$ integers$).$ Report the number of characters in the longest of these $3$ titles."
