What will the following algorithm display?

a ← 13
b ← 17
a ← a + 1
c ← a / 7
DISPLAY(c)
DISPLAY(a)
DISPLAY(b)

• 2 14 17

• 13 17 5

• 2 12 2

• 14 17 2

What will the following algorithm display?

a ← 13
a ← 17
a ← a + 1
DISPLAY(a)

• 13

• 17

• 18

• 19

What will the following algorithm display?

a ← "Milk"
a ← a + "Cookies Soda"
a ← a + "Chips"
b ← a + "put them in a bag so you know they stay crisp"
DISPLAY(b)

• Milk

• Milk Cookies Soda

• Put them in a bag and they stay crisp

• Milk Cookies Soda Chips put them in a bag so you know they stay crisp

a ← 13 MOD 26

DISPLAY (a)

• 26

• 13

• 8

• 0

What will the following algorithm display?

a ← 26 MOD 13
DISPLAY (a)

• 26

• 13

• 8

• 0

What is the percentage that this algorithm displays true?

DISPLAY(RANDOM(5, 9) > 9)

• 0%

• 20%

• 60%

• 100%

With Boolean, what does "A OR B" mean?

• Neither A or B can be true for the condition to be true

• If A is true, then the condition is true

• If B is not true, then the condition is always true

• Both A and B must be true for the condition to be true

What is the percentage that this algorithm displays true?

DISPLAY(RANDOM(1, 5) = 5 OR RANDOM(1, 5) = 9

• 20%

• 40%

• 60%

• 100%

What is the percentage that this algorithm displays true?

DISPLAY(RANDOM(1, 5) = 6 AND RANDOM(1, 5) ≤ 5)

• 0%

• 40%

• 60%

• 100%

y ← RANDOM ( 1, 10000) {

n ← RANDOM (0, 3)

REPEAT n TIMES{

if CAN_MOVE FORWARD ; MOVE_FORWARD ( ) }

p ← RANDOM (0, 1)

REPEAT p TIMES {

TURN_LEFT ( ) }

}
