Assignment Java-6 (Grains)
Purpose:  To learn the boundaries of int and long (accuracy), to become more familiar
with the java libraries.


 

There once was a wise servant who saved the life of a princess. The king promised to
 pay whatever the servant could dream up. Knowing that the king loved chess, the servant
 told the king he would like to have grains of wheat. One grain on the first square of a
 chess board. Two grains on the next. Four on the third, and so on.


 

There are 64 squares on a chessboard.


 

Write a program that shows how many grains were on each square and the total number of
 grains.


 

In other words, I want to type
