#1

one test is not passing this is my code
#include
using namespace std;
class node{
public:
int data;
node* lt;
node* rt;
node(int d){
data=d;
lt=NULL;
rt=NULL;
}
};
void buildbt(node* rot){
if(rot==NULL){return;}
string ls;
cin>>ls;
if(ls==“true”){
int dd;
cin>>dd;
node* tem=new node(dd);
rot->lt=tem;
buildbt(rot->lt);
}
string rs;
cin>>rs;
if(rs==“true”){
int dd;
cin>>dd;
node* tem=new node(dd);
rot->rt=tem;
buildbt(rot->rt);
}
}
void remlef(node* rot){
if(rot==NULL){return;}
if(rot->lt!=NULL){
if(rot->lt->lt==NULL&&rot->lt->rt==NULL){
rot->lt=NULL;
}}
if(rot->rt!=NULL){
if(rot->rt->lt==NULL&&rot->rt->rt==NULL){
rot->rt=NULL;
}}
remlef(rot->lt);
remlef(rot->rt);
}
void prnt(node* rot){
if(rot==NULL){
return;
}
if(rot->lt!=NULL&&rot->rt!=NULL){
cout<lt->data<<" => “<data<<” <= “<rt->data<<endl;}
else if(rot->lt==NULL&&rot->rt!=NULL){
cout<<“END =>”<data<<” <= “<rt->data<<endl;
}
else if(rot->lt!=NULL&&rot->rt==NULL){
cout<lt->data<<” => “<data<<” <= END"<<endl;
}
else{
cout<<“END => “<data<<” <= END”<<endl;
}
prnt(rot->lt);
prnt(rot->rt);
}
int main(){
int d;
cin>>d;
node* rot=new node(d);
buildbt(rot);
remlef(rot);
prnt(rot);
return 0;
}
