Seems tough to do as every time we dont know which coins we flipped in the previous move
We can perform all the four operation one by one in circular fashion and we will have probabilitty of getting all head up at some time. this is because even if table rotated at random, each of the for step will do different thing from previous step. I have not proofed it rigorously. It seems to be a solution to me comments appreciated... -- regards Jitendra -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
