"...removes all exclamation marks..."

True, I have no idea why I've decided to use this function

This technically shouldn't count as valid since it will consider strings containing numbers as okay.

Needle should be a string not an integer

Basically.

ahahahahahahah good

Thanks for the laugh xD

Khabi lame vibes here lol

Eval for people with no brain in their head...

I hate it too... I have been having headache trying to figure it out.. can you please teach me?...

You can use "reset" instead of getting [0] element from array.
Now you are using both ways to get a value from array, so it seems inconsistent.

why to traverse through array twice, so this solution will reduce the number of operations in half.

Empty array will result division by zero.
