For a List implemented with a linked-list, the method bool Reverse() is implemented as follows: void List::Reverse() { } if (front==NULL) return; Node *temp1, *temp2, *temp3; temp2=front; temp3=front->next; while (temp3!=NULL) { } temp1=temp3->next; temp3->next=front; //missing line temp3=temp1; temp2->next=NULL; The missing line should be: O a. front-temp2; O b. front-temp1; O c. temp2=NULL; O d. temp1-temp3; O front-temp3;

Question
For a List implemented with a linked-list, the method bool Reverse() is implemented as follows:
void List::Reverse() {
}
if (front==NULL) return;
Node *temp1, *temp2, *temp3;
temp2=front;
temp3=front->next;
while (temp3!=NULL) {
}
temp1=temp3->next;
temp3->next=front;
//missing line
temp3=temp1;
temp2->next=NULL;
The missing line should be:
O a. front-temp2;
O b. front-temp1;
O c. temp2=NULL;
O d. temp1-temp3;
O e. front-temp3;
