Define a class to accept a number and check whether it is a SUPERSPY number or not. A number is called SUPERSPY if the sum of the digits equals the number of the digits.

Example1:

Input: 1021
output: SUPERSPY number [SUM OF THE DIGITS = 1+0+2+1 = 4,
NUMBER OF DIGITS = 4 ]

Example2:

Input: 125
output: Not an SUPERSPY number [1+2+5 is not equal to 3]
