Implement an algorithm to delete a node in the middle of a single linked list, given only access to that node 
EXAMPLE
Input: the node ‘c’ from the linked list a->b->c->d->e
Result: nothing is returned, but the new linked list looks like a->b->d->e

#include <iostream>using namespace std;// Creating a Linked List:struct Node{    Node(int d):data(d){next = NULL;};    int data;    Node* next;};void printNode(Node* head){    cout<<"Print:"<<endl;    while(head != NULL)    {        cout<<head->data<<endl;        head = head->next;    }    cout<<"End"<<endl;};void deleteMid(Node* p){    if(p == NULL || p->next == NULL)         return;    Node *q = p->next;    p->data = q->data;    p->next = q->next;    delete q;};int main(){    Node* head = new Node(1);    head->next = new Node(2);    head->next->next = new Node(3);    head->next->next->next = new Node(4);    head->next->next->next->next = new Node(5);    head->next->next->next->next->next = new Node(6);    deleteMid(head->next->next);    printNode(head);    system("pause"); };
