How to take input in this?
@akh.chakraborty11
This particular problem asks you to take a generic tree input . A generic tree is a tree where any node can have any number of children (unlike binary trees where a node can have atmost 2 children).
The first integer in each row indicates the data at the node whereas the second integer indicates the no of children that node has .
