What is the purpose of the function makeTower in Karel's program?

The function makeTower is designed specifically to build a tower by placing balls. In Karel's programming environment, this function would typically contain a series of instructions that directs Karel to perform actions required to stack balls on top of each other, resulting in a vertical tower.

This could involve Karel moving to a designated position, placing a ball, moving up one space, and repeating the action until the desired height of the tower is reached. The focus on constructing a tower is a common task within Karel's challenges, emphasizing the use of loops and conditions to accomplish repetitive tasks efficiently. The implementation of this function showcases Karel's command capabilities, turning simple movements and actions into more complex structures through programming.
