Your question is Palindrome With One Deletion. Start with the requirements on the right.
Run and submit as often as you like. When you're ready, talk me through your approach or go straight to the code.
Navi uses short identifiers in parts of its application flows. Given a string s, determine whether it is possible to make s a palindrome by deleting at most one character.
Return True if s is already a palindrome or can become one after deleting exactly one character. Otherwise, return False.
Implement valid_palindrome(s), where s is a string. The function must return a boolean. Characters are compared exactly as provided, including case and non-alphanumeric characters. A deletion removes one character and preserves the order of all remaining characters.
