Length is generally supposed to be the longer measurement so that's why (l>w) works.

Sorry for late reply, I believe it's a bug. I was just printing the output and noticed that was the "correct" answer 😅

ha ha, how did you do it?

yes

PHP?????

why do you need to do (l>w)?

It is because I do not think about it, I just use === everywhere to ensure I am handling the values with the expected type.

why did you use === for checking odd or no the number? The function strlen () get the string length, so it's mean you have the number, but operator === usually using for string to avoid automatic convert to number.
