### 2. **How to Check if a String is a Palindrome Using Recursion in Python?**
**Question:** How can you check if a string is a palindrome recursively in Python?

**Answer:** A palindrome reads the same forward and backward. Here’s a recursive approach:

```python
def is_palindrome(s):
    s = s.lower().replace(" ", "")
    if len(s) <= 1:
        return True
    if s[0] != s[-1]:
        return False
    return is_palindrome(s[1:-1])

print(is_palindrome("A man a plan a canal Panama"))  # Output: True
print(is_palindrome("hello"))  # Output: False
