1 00:00:00,012 --> 00:00:04,460 >> Okay. Here's, here's an outline of the, of the 2 00:00:04,460 --> 00:00:09,551 problem solution. So we were asked to show that G is less 3 00:00:09,551 --> 00:00:14,947 than or equal to H. That's the same thing as showing H minus G 4 00:00:14,947 --> 00:00:18,756 is greater than or equal to 0. There's H. 5 00:00:18,756 --> 00:00:25,129 Here's minus G. So we, all we have to do is left moving 6 00:00:25,129 --> 00:00:32,749 second wins in this game. Now if right moves first, right's only 7 00:00:32,749 --> 00:00:39,403 move is to chop this. Now left has a move of chopping this. 8 00:00:39,404 --> 00:00:45,646 Now right has now moved leftwards.
