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 adds numbers. The `//` operator performs integer division and keeps the whole-number part. The `%` operator returns the remainder after division. `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 `n // 10 + n % 10` shows how this idea is applied to the task data.

Hints
+
['Tens are `n // 10`; ones are `n % 10`.']
ANSWER
Solution
+
n = int(input()) result = n // 10 + n % 10 print(result)
