There are three tall poles and some golden disks.有三根柱子和一串金盘。
The disks have different sizes.每个盘子大小不一样。
You must move the whole stack to another pole.你要把整摞盘子搬到另一根柱子上。
You can never put a big disk on a small one.大盘不能压在小盘上面。
More disks mean many more moves.盘子越多,要搬的次数多得吓人。
With 64 disks, it takes 2 to the 64 minus 1 moves.64个盘子要搬2的64次方减1次。
That would take billions of years to finish.搬完得花上几十亿年。
