In the Wild West, you challenge two cowboys, Hunter Jack and Sharp Shooter Leo, to a death match. They, being better shooters than you, readily accept your challenge. But they don't want to waste bullets and thus lay down certain rules that are accepted by you as well. Here are the rules:
1) Everyone shoots in a given order till only one is left.
2) Everyone shoots only once when his turn arrives.
3) If any one of you is injured, the other two will finish him off together.
4) The worst shooter (which is you) gets to shoot first and the best one shoots last.
Now, what tactics will you use if you know that you hit every third shot, Jack hits every second shot and Leo hits every shot?
