Not getting correct output

#1


Whats wrong with this code?

#2

pass index by reference
Node* CreateTree(vector ino,vectorpost,int s,int e,int& index)

#3

Yeah it worked!!but why it is coming wrong earlier?

#4

because you have to not pass it by reference :innocent:

actually the changes done while calling for right
root->right=CreateTree(ino,post,k+1,e,index);
will not reflect back for left call
which is wrong

i hope this help
if you have more doubts regarding this feel free to ask
if your doubt is resolved mark it as resolved from your doubt section inside your course

#5

Then,do we need to do it for start and end as well?

#6

why
s and e are different for left and right
