Am I right in thinking that
(โ€œ0_0 (: /-\ :slight_smile: 0-0โ€)

is not a palindrome? The character between the first two zeros is an underline โ€œ_โ€. The character between the last two zeros is a dash โ€œ-โ€. Donโ€™t the those two characters need to be identical to satisfy the palindrome requirement?

The editor is turning the : + ) characters into a smiley face, by the way, and I donโ€™t know how to prevent this.

Note
Youโ€™ll need to remove all non-alphanumeric characters (punctuation, spaces and symbols) and turn everything lower case in order to check for palindromes.


#3

understood. but the term above (but not with an emoticon) is given in the FCC challenge.


#4

I think I know what youโ€™re saying. The code should make everything lower case, which will eliminate the difference.

Tricky.

Thank you.
