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. Comparison operators `==`, `!=`, `<`, `>`, `<=`, `>=` compare values and produce `True` or `False`. `if` checks a condition and runs its block when the condition is true. `else` runs when the corresponding `if` condition is false. `print()` displays the program result. Print only what the problem statement requires.
**Connection to this task.** An `if` statement chooses a program branch from a Boolean condition. Comparisons produce `True` or `False`, and `elif` lets you test several mutually exclusive cases in order. The expression `'CHILD'` 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: “Age Check”.** The same basic mechanism is used in a different context here, so understand the operation itself rather than memorizing a finished line of code.

ANSWER
Solution

age = int(input())
if age < 14:
print('CHILD')
else:
print('TEEN_OR_ADULT')
