https://ide.codingblocks.com/s/226140 The sum is calculated correctly but i m not able to take input pls tell how to do it

@Madhavendra-Gupta-2240591552663161 you are told that first root is given, then number of children (in preorder form, ie root, left, right). So for input
1 2
2 2
3 0
4 0
5 2
6 0
7 0
2

we make a root 1 and it has 2 children. we call function for left child.
root is 2 and it has 2 children. again calling for left child.
root is 3 and it has 0 children, so we dont call the function, and consequently return to the previous call. now we call for the right child of 2 and so on

I hope you are getting it now.

#3
