Problem Statement

An automorphic number is an integer whose square ends in the same digits as the number itself. For example, `25^2 = 625` (ends in 25) and `76^2 = 5776` (ends in 76). Given an integer `n`, return `true` if `n` is an automorphic number, and `false` otherwise. ### Constraints - `1 <= n <= 10^5` ### Input Format A single line containing the integer `n`. ### Output Format Print `true` or `false`.
