Hey @vanshgupta
root Node is private
class ke bahar access nhi hoga.
mujhe display fun ko call krna h. mere paas root Node ka address hona chahiye .
public void display() {
display(this.root);
}
user bahar se display() fun ko call karega.
internally ye display(this.root); fun call hoga
koi aur confusion hoga to aaj class me discuss kr lenege.
