Can someone help me with this program in python? Using this code how can I use the stopwatch module to filll out this table Use the stopwatch module to estimate how long your program runs. stake - initial amount you start with goal - the amount you want to end with (you will either lose it all or make your goal) trials - the number of times you want to run the experiment - run the experiment 100 times to get a more accurate estimate of the probability. Do any empirical analysis using the doubling method. Start with the stake = 500 and goal 1000 and continue to double until the stake = 1000000.
