Suppose we have a 5 x 5 pixel image.  The pixels in the top row are numbered 0 through 4 left to right, the ones in the second row from the to are numbered 5 through 9 left to right, and so on.  Suppose this image contains a '+' symbol at the center, and the bars in the '+' are 1 pixel wide and 3 pixels long, with the central pixel appearing in both the horizontal and vertical bars.  The pixels corresponding to the '+' have value 1 and others have value 0.

8.What is the value of the pixel numbered 6?
Ans:0

9.How many pixels have value 1?
Ans:5

10.What are the numbers of pixels with value 1?

Suppose you decide to represent the cards in a standard deck using the numbers 1 through 52.  So for this, the cards are arranged so that the clubs come first, then the diamonds, then the heards and then the spades.  Also within a suit, the order of the cards is ace, then the cards 2 through 10, then the jack, then the queen, then the king.  So after arranging the cards in this manner, the ith card is assigned the number i.  Thus the king of spades will get the number 52, and the ace of clubs the number 1.

11.What number does the 9 of spades get?
Ans:48
-------------------------------------------------------------------------------------------------------------------
12.Suppose some card has number n.  I would like to know if it is a diamond.  Which of the following tests will tell me if this is the case?
 i->n > 26
 ii->ceiling(n/13) = 2
 iii->n mod 13 = 0
 iv->floor(n/13) = 2
-------------------------------------------------------------------------------------------------------------------------
13.When you multiply an n digit number by an m digit number manually, then number of digit wise multiplications you perform is:
 i->m*n
 ii->m+n
 iii->m/n
 iv->m-n
--------------------------------------------------------------------------------------------------------------------------
14.Give a machine language program which computes the cube of the number stored in address 100 and stores in address 200.

Hint: 1) Modify the fourth power program from the lecture slightly.

2) Write the answer as space separated numbers  (exactly one space) with no leading or trailing space.
Ans:57 100 100 100 100 57 100 100 100 20.
