The goal: Any language. The smallest function which will return whether a string is a palindrome. Here is mine in Python:
R=lambda s:all(a==b for a,b in zip(s,reversed(s)))
50 characters.
The accepted answer will be the current smallest one - this will change as smaller ones are found. Please specify the language your code is in.
7 characters in J: Not sure if this is the best way, I'm somewhat new to J :)
p=:-:|.
explanation: |. reverses the input. -: compares. the operands are implicit.
p 'radar'
