The Karel program turns Karel to face north and builds a tower by placing balls in a loop until an obstacle is encountered, representing the top of the world.The provided Karel program begins by ensuring that Karel is facing north using the `checkNorth` and `turnNorth` functions. The `checkNorth` function is not explicitly defined in the given code, but it seems to be intended to check Karel's orientation. The `turnNorth` function, on the other hand, consistently turns Karel to face north, regardless of the initial direction.After facing north, the program enters a loop (`while (notFacingNorth())`) where Karel keeps turning left until facing north. Once Karel is oriented north, the `turnNorth` function is called to ensure the correct direction. Following this, the `buildTower` function is invoked to construct a tall tower.The `buildTower` function uses a `while (frontIsClear())` loop to execute the following steps repeatedly: Karel places a ball, moves forward, and places another ball. This loop continues until Karel encounters an obstacle, presumably reaching the top of the world. The result is a tower built by placing balls at each step of Karel's movement.In summary, the Karel program ensures Karel faces north, then constructs a tower by placing balls in front of it, moving forward, and repeating the process until an obstacle is encountered, signifying the top of the world.The question probable may be:How does the provided Karel program function to draw a tall tower from Karel's starting position, and what role do the `turnNorth` and `buildTower` functions play in achieving this task?This program draws abig tower from Karel's starting spot.funtion start () {checkNorth () ;while (notFacingNorth()) {turnLeft();}turnNorth();buildTower () ;}// This function has karel face north, no matter what direction// karel starts facing.function turnNorth () {turnLeft() ;}}// This function builds a tower all the way, to the top of the world.function buildTower () {while (fronsIsClear ()) {putBall ();move();putBall ();}}...
