What is "10 20"
Assuming that "forward" tells a robot to move forward by 10 pixels and "turn" tells it to turn right by 90 degrees, this shape would be drawn by the following algorithm:
forward forward turn forward turn forward forward turn forward turn

DISPLAY ("EVEN")
}
This is a Boolean expression that could replace MISSING CONDITION.
What is "num MOD 2 == 0"
This is responsible for converting URLs to IP addresses.
What is the Domain Name System (DNS)?

num <- 0
IF (z){
num <- num + 1 }
IF (NOT(x AND NOT(y)){
num <- num + 2 }
IF (( x AND (5 > 2) ) OR ( y AND z )){
num <- num + 3 }
DISPLAY num
What is "4"?
In determining the best route to take on a trip, a maps application gave the user an expected arrival time based on traffic patterns, road construction, and roadways. The arrival time was off of the actual time by a minute, though. This answer refers to the method for choosing a solution that is a satisfactory, even if not necessarily the most optimal, solution in a reasonable amount of time.
What is a heuristic solution/approach?
A computer program uses 3 bits to represent integers. When the program adds the decimal (base 10) numbers 5 and 3, the result is 0, this type of error occurred.
What is an overflow error?
i <- 0
sum <- 0
REPEAT UNTIL i = 4{
sum <- (sum + i)
i <- (i + 1)
}
DISPLAY (sum)
What is "6"?
