Mapped string question

what is the mistake in my code??

if your are using string
then use push_back() and pop_back() function

you can see it in modified code

there are some other unneccasary parameters in your code
like j and e if you want you can remove them

in base case use can use
if(s[i]=='\0')

if you have more doubts regarding this feel free to ask
i hope this helps
if yes hit a like :heart:: and don’t forgot to mark doubt as resolved :grinning:
