Why am I getting -1 as output? Can you tell whats wrong

#1
#2

hello @akash_281

when u are htting if(root==target) then from here u need to return 0. which u r not doing

#3

Fixed it but it’s still showing -1

#4

becuase u have create a new node for 2. then its obvious that it will have different address from the tree nnode hence it is giving -1.

u need to find the address of tree nodewith data 2.

or instead of comparing address compre data value

#5

Understood but how to take the input then? If my target node has a value of 2
if I do something like root->left I am getting the correct ans but is there any other way because if my tree is huge this is not sustainable.

#6

compare data instead of address.
