State Pattern $-$ A Lamp has three states that it rotates through when a button is pressed: OFF $$ BRIGHT $$ DIM. The Lamp starts in the OFF state. Complete the UML by drawing the missing Lamp class with its methods and all connections. Then complete the code. In the main, construct a lamp and switch it to the BRIGHT state. $15pts.$
