Copying Linked Lists with Random Pointers 两个方法:方法一: 1.不考虑随机指针的情况下复制链表: 2.在复制过程中建立一个以原链表节点地址为key,相应的复制链表节点地址为value的hash: 3.遍历原链表和新链表,得到原链表随机指针值,并复制给新链表. 方法二: 1.忽略随机指针值复制链表第n个节点并插入到第n个节点与第n+1个节点之间,以此为方式修改链表直到链表尾. 2.利用链表节点next指针指向节点的的拷贝这一已知,使用如下语句: srcC…

Write a program to find the node at which the intersection of two singly linked lists begins. Notice If the two linked lists have no intersection at all, return null. The linked lists must retain their original structure after the function returns. Y…
