Can anyone share his approach or idea of solving this beautiful problem. I couldn't get any way to solve this.The tutorial given , is in japanese. I used the google translate and whatever little i got to know is that we only need to check if it is possible to reach the bottom rightmost cell of a grid of size(h*((2h-1)*w)) form (1,1).If it is, then the answer is yes,else no. Please, reply if someone can help!
