Reminds me of a story. A wise man was called to solve a problem for the Emperor, and he did so. The Emperor asked what he could give him as a reward. The wise man said humbly, "I do not ask for much. I wish for a chess board with one grain of rice on the first square, two grains on the second square, four grains on the third square, and so forth." The Emperor agreed. Any idea on how the story ends?
