Narcissus number refers to an n-bit positive integer (n>=3), and the sum of the n power of each number is equal to its own. For example: 153=1*1*1+5*5*5+3*3*3,153 is a three-digit number, and the sum of three times of each number is equal to 153. The Python language is used to find out the number of daffodils between 100~999. Analysis process: The positive integer n of the single-digit 10-bit hundred are taken out, and then the sum of power; single-digit hundred better split, 10-bit words can be
