In MATLAB, the script should use both for and while loops.

Game Mode: Randomly generates 10 unique (e.g. non-repeating) multiplication problems that involve multiplying the integer selected in the previous step by an integer value between 2 and 12, inclusive, after which the following report should be displayed in the Command Window.

You correctly answered __ out of __ problems (__%) involving __s.

The number of correctly answered problems appears in the first blank, the total number of problems appears in the second blank, the percentages of problems answered correctly appears in the third blank, and the integer the user selected in step 1 appears in the last blank.

-- After completing a round of the game, the user should have the option to play another round or quit the game.
