Why my code is giving error
hello @kundankumarsports2
please check ur previous ,
i have already explained u the reason.
u need to change the logic of ur build tree function
Ya I checked please check this one and if any mistake is there in this correct it
in place of this function->

use this ->

because we r given level order (and not preorder)
The code what you gave me is of bfs please check it
yeah it is bfs code. and that is how we construct tree from given level order traversal (if still it is not clear then pls check input format of thr problem)
