Write a programme to check whether given input is palindrome or notConstraintsABC != PalindromeMAM == Palindrome123 != Palindrome151 == Palindrome

Step 1: Break Down the Problem

1. We need a function to check if a given input string is a palindrome.
2. A palindrome reads the same forwards and backwards.
3. We should consider case sensitivity and ignore spaces and special characters.

Step 2: Relevant Concepts

• A string is a palindrome if the reversed string is equal to the original string.
• We can use slicing to reverse the string in Python.

Step 3: Analysis and Detail

1. Define a function is_palindrome that takes a string as input.
2. Normalize the string by converting it to lower case and removing non-alphanumeric characters.
3. Reverse the string and compare it to the original normalized string.

Step 4: Verify and Summarize

• We can test the function with provided constraints:
  • "ABC" should return False.
  • "MAM" should return True.
  • "123" should return False.
  • "151" should return True.

Final Answer

Here is the Python code to perform the palindrome check:

def is_palindrome(s):
    # Normalize the string: convert to lower case and remove non-alphanumeric characters
    normalized = ''.join(char.lower() for char in s if char.isalnum())
    # Check if the normalized string is the same as its reverse
    return normalized == normalized[::-1]

# Test the function with the provided inputs
print(is_palindrome("ABC"))  # Output: False
print(is_palindrome("MAM"))  # Output: True
print(is_palindrome("123"))  # Output: False
print(is_palindrome("151"))  # Output: True

This program effectively checks for palindromes according to the specified constraints.
