Monthly Challenge #1: Palindrome 🔤

Welcome to Codédex's first ever Monthly Twitter Challenge! This one is created by our SWE Intern, @asiqurrahman. 🙌

Palindrome:

A word, sentence, or number that reads the same forward or backward (e.g., racecar, civic, and 121).

Challenge:

Create a Python function that:

  1. Takes in a string as a parameter.
  2. Checks if it's a palindrome.
  3. Returns True if it is or False if it's not.

Requirements:

  • 📦 Don’t use any packages.
  • 💬 Make sure to comment the code.

Post your program screenshot in the Twitter thread.

And we will pick a random winner by noon this Friday. The prize is a free Codédex tee and bragging rights! 🏆


Update:

We have a winner to the Codédex Monthly Challenge: Palindrome! 🥁...

Congrats to Michael Gonzalez! 🇪🇨

Why only Python, why not open to all coding languages ;)

Ex. Solution in C#

public static bool IsPalladium(this string text)
        {
            return text.SequenceEqual(text.Reverse());
        }

True! Only doing it for Python for now since codedex.io only has Python :(

Also, one line answer! 🙌 Shared the the team!

I guess..

def IsPalindrome(txt: str):
    length = len(txt)
    oddOrEven = 1 if length%2 else 0
    return txt[:length//2] == txt[length:length//2-1+oddOrEven:-1]

forTheGiggles = lambda txt: txt == txt[::-1]
Enter fullscreen mode Exit fullscreen mode
