A word is a palindrome when it reads the same forwards and backwards. Capital letters do not matter.

Read one word and print Yes if it is a palindrome, otherwise No.

No

Try the problem first. Open one hint at a time.

Hint 1

Change the case first so L and l match.

Hint 2

Compare the word with its reversed slice.

Write your Python code, run it on the examples and submit it to hidden tests.
