Automorphic number
Detailed guide and Python implementation for the 'Automorphic number' problem.
Problem Statement
Write a function is_automorphic(n) that takes a non-negative integer n and returns True if n is an automorphic number, or False otherwise. An automorphic number is a number whose square ends with the number itself. For example, 25 is automorphic because 25^2 = 625, which ends with 25.
- •0 <= n <= 10^6
Examples
n = 25
True
25^2 = 625. The last two digits of 625 are 25, which matches n.
n = 76
True
76^2 = 5776. The last two digits of 5776 are 76, which matches n.
n = 13
False
13^2 = 169. The last two digits of 169 are 69, which does not match 13.
