What happens when Karel runs 'turnLeft()' four times in succession?

When Karel runs the command 'turnLeft()' four times in succession, it effectively rotates in place a full 360 degrees, returning to its original direction. Each 'turnLeft()' command rotates Karel 90 degrees to the left. Therefore, after the first turn, Karel faces left, after the second turn, Karel faces away from its original direction, after the third turn, it faces right, and finally, after the fourth turn, Karel ends up facing in the same direction it started. This is why the answer correctly identifies that Karel rotates to face the same direction after completing four left turns. The phenomenon can be compared to the behavior of a circle, where a full rotation leads back to the starting point. This aspect of Karel's movement is fundamental in understanding directional commands and rotations in programming contexts.
