如题: 输入一个复杂链表(每个节点中有节点值,以及两个指针,一个指向下一个节点,另一个特殊指针指向任意一个节点),返回结果为复制后复杂链表的head。(注意,输出结果中请不要返回参数中的节点引用,否则判题程序会直接返回空)public class Solution { /* public class RandomListNode { int label; RandomListNode next = null; RandomListNode random = null;
RandomListNode(int label) {
this.label = label;
}
} */ public class Solution { public RandomListNode Clone(RandomListNode pHead) { if(pHead==null){ return null; } RandomListNode pCur =pHead; //复制next 如原来是A->B->C 变成A->A’->B->B’->C->C’ while(pCur !=null) { RandomListNode p = new RandomListNode(pCur.label); q = pCur.next pCur.next = p; p.next = q; pCur = q; } pCur = pHead; //复制random pCur是原来链表的结点 pCur.next是复制pCur的结点 while(pCur!=null){ pCur.next.random = pCur.random.next; pCur = pCur.next.next; } RandomListNode head = pHead.next; RandomListNode cur = head; //拆分链表 while(pCur!=null){ pCur.next = pCur.next.next; if(cru.next!=null){ cur.next = cur.next.next; cur = cur.next; pCur = pCur.next; } return head; } }
