Use a constant to determine at which number your program begins the countdown. You can choose which number (please don't make it too high, or it'll take me forever to grade your lab, ha!). Print a message to the user that says this program will selfdestruct in that number of seconds. Using either a or loop, print the count-down, with a 1 second delay between each number. If you a library named , you can use the function to sleep a specified number of seconds: End your countdown after printing zero (0). Print a self-destruct message, and then exit the program
