In this section, you will help Steve to develop and refactor his tower defense game in a functional programming way.

Exercise 1

Name and count all expressions and all statements in the code snippet below:

Tower mainTower = new(position: new Vector2(5, 5));
for (int level = 1; level <= mainTower.MaxLevel; level++)
{
     double upgradeCost = 100 * Math.Pow(1.5, level - 1);
     Console.WriteLine($"Upgrading to level {level} costs {upgradeCost} gold");
     if (playerGold >= upgradeCost)
     {
                  mainTower.Upgrade();
                  playerGold -= upgradeCost;
     }
}

Exercise 2

Refactor the code below to use expressions instead...
