single linked list版本:
void reverse(Node head){
Node cur = head;
Node prev = null;
while(cur != null){
Node nextNode = cur.next;
cur.next = prev;
prev = cur;
cur = nextNode;
}
return prev;
}
double linked list版本:
void reverse(Node head){
Node cur = head;
Node prev = null;
while(cur != null){
Node nextNode = cur.next;
cur.next = prev;
cur.prev = nextNode;
prev = cur;
cur = nextNode;
}
return prev;
}
我认为好像只有多一个prev node的设置, 还有别的需要考虑的地方吗?
感谢解惑!
