R

LL

LR

NOTE:LL mean left of root->left
code:
#include <iostream>
using namespace std;
struct node{
int data;
node *left;
node *right;
};
node* create(int data){
node *temp=new node();
temp->data=data;
temp->left=NULL;
temp->right=NULL;
return temp;
}
void print(node *root){
if(root=NULL)
return;
cout<<root->data<<endl;
print(root->left);
print(root->right);
}
int main() {
int n,r;
cin>>n>>r;
string s;int a;
node* root=create(r);
int t=n-1;

while(t--)
{ cin>>s>>a;
node *temp=root;
for(int i=0;i<s.length();i++){
if(s[i]=='L')
{ if(temp->left==NULL)
temp=create(a);
else
temp=temp->left;
}
else
{ if(temp->right==NULL)
temp=create(a);
else
temp=temp->right;

}
//cout<<temp->data<<" ";
}
delete(temp);

}
print(root);

}

Answer 1

It's helpful to other people if you share the code in the playground instead of in question. Easier to read, plus people can test it without retyping the whole thing.

Answer 2

Is the problem that it will not print, or will not print in order?

Answer 3

The delete (temp);
before the
print (root);
might cause a problem.
Also the logic for adding the nodes doesn't look right.
With only one delete this will leak memory, but this will not be stopping you from printing the data.

Please put in the code playground.

Answer 4

IT WORKS:(PROBLEM SOLVED)
#include <iostream>
using namespace std;
struct node{
int data;
node *left;
node *right;
};
node* create(int data){
node *temp=new node();
temp->data=data;
temp->left=NULL;
temp->right=NULL;
return temp;
}
void print(node *root){
if(root==NULL)
return;

print(root->left);
print(root->right);
cout<<root->data<<endl;
}

int main() {
int n,r;
cin>>n>>r;
string s;int a;
node* root=create(r);
int t=n-1;
node *temp=root;
while(t--)
{ cin>>s>>a;

for(int i=0;i<s.length();i++){
if(s[i]=='L')
{ if((temp)->left==NULL)
(temp)->left=create(a);
else
temp=(temp)->left;
}
else
{ if((temp)->right==NULL)
(temp)->right =create(a);
else
temp=(temp)->right;

}
// cout<<temp->data<<" ";
}
//delete(temp);

}
print(root);
// cout<<root->data;

}

Answer 5

there is some error therefore it is not printing the tree

Answer 6

i put it in code playground
