Theory for this problem
+
`input()` reads data entered by the user. The result of `input()` is initially a string. `split()` separates one input line into individual values using spaces. `map()` applies the specified conversion to each input value. Comparison operators `==`, `!=`, `<`, `>`, `<=`, `>=` compare values and produce `True` or `False`. `or` requires at least one condition to be true. `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 `'YES'` shows how this idea is applied to the task data.

['Outside means `n < left or n > right`.']
ANSWER
Solution
+
n, left, right = map(int, input().split())
if n < left or n > right:
print('YES')
else:
print('NO')
