how do I deal with the true and false input

#2

Hey @raghav007

node* buildTree()
{
    string d;
    cin>>d;
    if(d=="false")
    {
        return NULL;
    }
    node *root=new node(stoi(d));
    root->left=preorder_input(root->left);
    root->right=preorder_input(root->right);
    return root;
}

Do a dry run I havent checked if its working or not

#3

will it work when d is true because it will convert d to an int. if that’s the case maybe we should write else if(d == true) and then cin>>d once again

#4

did you mean to write build here instead of preorder?
