i have a severe skill issue, my solution took 90 lines of code XD. thanks for the great explanation

[@GregHogg]

That's really impressive honestly 🤣

[@jamesholland6140]

Dude the way you explain is really something!!!

[@anirbandas12]

How to do it without stack?

[@bhaskarkukreti2272]

With vector

[@chandlerkenworthy3185]

I would note that you can add at the top a base case of if (len(s) % 2 != 0): return False

its amzing to follow along and to understand how to actully solve it thankyou for that! but can u give me an advice on how can i myself think of solution and implement in code because no way i would have apprached the way do to a solution so can u give an advice on logic building or apporaching? thankyou

[@GregHogg]

If you watch enough of these solutions and practice it yourself, that gives the highest likelihood you'll be able to solve a new one :)
