A palindrome is a word that is identical forward and backwards.

  • mom
  • racecar
  • kayak

Given a word, create a function that checks whether it is a palindrome.

Examples

is_palindrome("mom") ➞ true

is_palindrome("scary") ➞ false

is_palindrome("reviver") ➞ true

is_palindrome("stressed") ➞ false

Notes

All test input is lower cased.
