Adding two linked list

you have two linked list for two decimal numbers means

if there r two no..........3627809 & 234
two linked list will be

1.  3->6->2->7->8->0->9->NULL

2.  2->3->4->NULL

your output linked list will be

3->6->2->8->0->4->3->NULL
Answer -
First reverse both the lists and then add. After adding reverse the resulted linked list. Code is as follows -

linked list p,q, result;



int x=0,num;



p=reverse(p);

q=reverse(q);





while(p!=NULL  || q!=NULL)

{

 num=p->data+q->data+x;

 

 result->data=num%10;

 x=num/10;

 

 p=p->link;

 q=q->link;

}

if(p!=NULL)

{

 p->data=p->data+x;

 add their nodes at the back;

}





if(q!=NULL)

{

 q->data=q->data+x;

 add their nodes at the back;

}

result=reverse(result);
