However, when he opened the letter, it said, "The Queen put the wrong box."

The king's reward

Legend has it that Indian King Shehan intends to reward Sass Bandal, the inventor of chess. The wise minister knelt before the king and dared to say, "Your Majesty, please give me a grain of wheat in the first box, two grains in the second box and four grains in the third box. At this speed, each compartment is twice as big as the previous one. Your Majesty, give all the 64 grains of wheat like this on the chessboard to the servant? " The king said, "Your request is not high, and you will get it." . With that, he ordered a bag of wheat to be taken to the throne, and the work of counting wheat grains began. ..... Before the 20th cell, the bags were empty, and bags of wheat were transported to the king. However, the number of wheat grains increased rapidly one after another, and it soon became clear that even if all the food in India was taken out, the king could not fulfill his promise to the inventor of chess.

How many grains of wheat should the king give the chess inventor? (1+2+4+8+...+2 to the 63rd power =2 to the 64th power-1= 6544674073709551615 (grain))
