Theory for this problem
+
`input()` reads data entered by the user. The result of `input()` is initially a string. `int()` converts a numeric string into an integer. The `%` operator returns the remainder after division. `print()` displays the program result. Print only what the problem statement requires.
**Connection to this task.** The `%` operator returns a division remainder. Therefore `n % k` is useful for divisibility checks and for working with the last digits of a number. The expression `n % 10` shows how this idea is applied to the task data.
