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]
