Based on the half-written tic/tac toe game code below. Construct code for the "do_computer_move" function in the attachments. Follow what the algorithm and and signature says. Make sure the computer controls the game piece, "O".  Same goes for the "check_game_over" function in the attachments. Lastly, the "user_clicks" functions presented in the code below must be put inside the "do_user_move" function in the attachments and it must return a bool. In this function, make sure the user still controls the game piece, "X". For all functions, it must follow the signature and algorithm stated. 

Lastly, all the functions must correspond to the function calls in the "clickhandler" function and the "main" function that runs the entire game in the attachments .  Use the time module, random module, and turtle module wherever needed. Please make sure the turtle can go fast, especially when the user clicks on the board to make their move and when the computer  makes its move. But do not use turtle.speed as it is inside the prohibited methods section. The "main" function provided in the attachments uses turtle.tracer to make it go faster. Everything must be in the appropriate functions in the attachments. Do NOT create your own functions. 

  

Prohibited methods: These are inadequate with the code already written at the bottom:

turtle.speed

turtle.pen() or turtle.Turtle

turtle.screen or turtle.getscreen

turtle.shape, turtle.shapsize, turtle.resizemode, turtle.turtlesize

tkinter or any other built-in functions besides turtle, time or random

Here is my code:

def clickhandler(x, y): signature: int, int -> None Type This function is called by turtle in response to a user click. The parameters are the screen coordinates indicating where the click happened. The function will call other functions.
