Q:

How would you reverse a doubly-linked list?

Answer

This problem isn't too hard. You just need to start at the head of the list, and iterate to the end. At each node, swap the values of pNext and pPrev. Finally, set pHead to the last node in the list.


Node * pCurrent = pHead, *pTemp;


while (pCurrent)


{


  pTemp = pCurrent->pNext;


  pCurrent->pNext = pCurrent->pPrev;


  pCurrent->pPrev = temp;  


  pHead = pCurrent;


  pCurrent = temp;


}
