def is_palindrome(s):
"""
Checks if a string is a palindrome (reads the same backward as forward).
Args:
s: The input string.
Returns:
True if s is a palindrome, False otherwise.
"""
processed_string = ''.join(filter(str.isalnum, s)).lower()
return processed_string == processed_string[::-1]
# Test case
print(is_palindrome("racecar")) # Output: True
```
