🚀 Day 33/150 – Palindrome Number in Python

 🚀 Day 33/150 – Palindrome Number in Python

A Palindrome number is a number that remains the same when reversed.
Example: 121, 1331, 454 are palindrome numbers.

Let’s explore different ways to check palindrome number in Python 👇

🔹 Method 1 – Using while Loop

n = 121
temp = n
rev = 0

while n > 0:
    digit = n % 10
    rev = rev * 10 + digit
    n //= 10

if temp == rev:
    print("Palindrome Number")
else:
    print("Not Palindrome")

\✅ Best numeric method.

🔹 Method 2 – Taking User Input

n = int(input("Enter a number: "))
temp = n
rev = 0

while n > 0:
    digit = n % 10
    rev = rev * 10 + digit
    n //= 10

print("Palindrome" if temp == rev else "Not Palindrome")

✅ Useful for dynamic programs.

🔹 Method 3 – Using String Slicing

n = 121

if str(n) == str(n)[::-1]:
    print("Palindrome")
else:
    print("Not Palindrome")

✅ Shortest and easiest method.

🔹 Method 4 – Using Function

def is_palindrome(n):
    return str(n) == str(n)[::-1]

print(is_palindrome(121))

✅ Reusable and clean approach.
