`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 performs integer division and keeps the whole-number part. The `%` operator returns the remainder after division. Comparison operators `==`, `!=`, `<`, `>`, `<=`, `>=` compare values and produce `True` or `False`. `if` checks a condition and runs its block when the condition is true. `print()` displays the program result. Print only what the problem statement requires.

**Connection to this task.** The `//` and `%` operators complement each other: the first gives the integer quotient and the second gives the remainder. This is useful when splitting a number into groups or digits. The expression `m` shows how this idea is applied to the task data.

For this task, pay special attention to `int(input())`: it connects the concept above to the concrete computation or program action.

**Focus: “Smallest Digit”.** The same basic mechanism is used in a different context here, so understand the operation itself rather than memorizing a finished line of code.
