Now, let's solve the next Python Coding Interview Question: *3. Check for Palindrome* *Problem Statement:* Determine if a given string is a palindrome (reads the same backward as forward). *Approach 1: Using String Slicing* def is_palindrome(s): s = s.lower().replace(" ", "") # Optional: normalize the string return s == s[::-1] # Example usage: word = "Madam" print("Is palindrome:", is_palindrome(word)) *Explanation:* - s[::-1] gives the reversed string. - Compare the original string with its reverse. - Used .lower() and .replace(" ", "") to handle case and spaces (optional). *Approach 2: Using a Loop* def is_palindrome(s): s = s.lower().replace(" ", "") left = 0 right = len(s) - 1 while left < right: if s[left] != s[right]: return False left += 1 right -= 1 return True # Example usage: word = "RaceCar" print("Is palindrome:", is_palindrome(word)) *Explanation:* - Two-pointer technique: compare characters from both ends. - Efficient for long strings.
