Hanoi Tower: This is a puzzle toy derived from an old Indian legend.When the great brahma created the world, he made three pillars of diamond. On one pillar, 64 discs of gold were stacked from bottom to top in order of size.The great brahman ordered the brahman to reposition the disks in order of size from below on another pillar.It was also stipulated that the disks could not be enlarged on small disks, and that only one disk could be moved at a time between the three pillars. It is estimated that it would take more than 584.554 billion years to remove 64 pieces of gold. The earth is only 4.5 billion years old, and the life expectancy of the solar system is said to be in the tens of billions of years.After 584.554 billion years, perhaps all life on earth has long since disappeared.
