@Divya_321 hey divya modify your code according to this
int intersection(node * head1,node * head2){
node*temp=head 1;
while(head2!=NULL){
while(head1!=NULL){
if(head1->data==head2->data){
return head1->data;
}
head1=head1->next;
}
head1=temp;
head2=head2->next;
}
return-1;
}

@Divya_321 hey divya in your code I think you’re returning the zero but question demand for the -1 if intersection is not found.
