hi @abhishekchoudhary05112000_e0b1866595b5a9d4
Have a look at this code–>

#include<bits/stdc++.h>
using namespace std;
class node{
	public:
	int data;
	node*left;
	node*right;
	node(int d){
		data=d;
		left=right=NULL;
	}
};
void buildTree(node*&root){
	string left,right;
	int d;
	cin>>d;
	root = new node(d);
	cin>>left;
	if(left == "true"){
		buildTree(root->left);
	}
	cin>>right;
	if(right == "true"){
		buildTree(root->right);
	}
}
bool areIdentical(node* root1,node* root2){
	if(root1==NULL and root2==NULL)
	    return true;
	return (root1 && root2) && areIdentical(root1->left,root2->left) && areIdentical(root1->right,root2->right);
}
int main() {
    node* root1=NULL;
	node* root2=NULL;
	buildTree(root1);
	buildTree(root2);

	if(areIdentical(root1,root2)){
		cout<<"true"<<endl;
	}else{
		cout<<"false"<<endl;
	}
	return 0;
}

You have to print “true”, “false” like this
