I have tried. I just reset it after I couldn't figure out how to do it. Here is the rest of the question.
Integer indexing array: Weekend box office
The row array movieBoxOffice stores the amount of money a movie makes (in millions of $) for the 7 days of a week, starting with Sunday. Write a statement that constructs a row array weekendBoxOffice having the values for Sunday, Friday, and Saturday.
Ex: If movieBoxOffice is [5.6, 3.5, 1.1, 1.5, 0.8, 1.2, 1.9], then weekendBoxOffice is [5.6, 1.2, 1.9].
I originally tried weekendBoxOffice = [1, 6, 7]. The answer was weekendBoxOffice = movieBoxOffice([1,6,7])
