Create a main() function for your program. The purpose of this function is to control the game logic for a Power Quiz game. The steps of this game are as follows: Set the user's score to 0. ● Generate a random integer n in the range [1,128] inclusive. Ask the user to enter the corresponding binary number for n. Use your binary_to_decimal() function to find the correct answer. Check if the user's answer is correct or not O If correct, add 1 to their current score O If not, tell them the correct answer. Repeat these steps until the user types "stop" in place of a number. If the user types "stop", your program should print out their final score and terminate the game. Finally, add the following code to the end of your program to make main() function work. Note those '' are two underscores '__'. if name main() Print == 11 '___main__": Activity Details
