Sir in this you are adding child value in ArrayList but parent node data is not added in ArrayList!
can you elaborate on these things because I am getting confused that how we fetch the value of the root node when we need it
Parent nide value add
@saurabhananta It happens at the end of recursion.
for example:
this.data=data;
this.children=new arraylist();
this.data stores the value in the data variable.
HI @saurabhananta
each node of the tree contains two parameter one is the data and the other one is arraylist of children nodes.
so after adding children into the arraylist we assign value parent node in the data parameter.
