After the power of 2 is written in binary form, it is easy to find that there is only one 1 in binary, and 1 followed by n 0; therefore, the problem can be converted to determining whether n zeros are followed by 1. If we subtract this number from 1, we will find that the only one will change to 0, and the original n 0 will change to 1; therefore, the original number and the number after the first subtracti
