Once upon a time in an ancient kingdom of Montarek. A peasant saved the life of the princess. The king would reward him with anything he would like. The currency in Monterek is called a Ruba:
Here is the request:
The peasant said I would like the King to place...
- 1 ruba on the first square on my chest board.
-2 rubas on the second square.
-4 rubas on the third square
-8 rubas on the fourth square.
Continue this pattern until you have covered all 64 squares. Each square should have twice as many rubaas as the previous square.
The Kind replied, "Rubas are the least valuable coin in the kingdom. Surely you can think of a better reward." But the peasant insisted, so the king agreed to his request.
Did the peasant make a wise choice?
