2.6Given a circular linked list,  implement an algorithm which returns the node at the beginning of the loop. 快指针和慢指针一起在头指针开始移动,快指针每次移动两步,慢指针每次移动一步,直到相遇, 相遇后,把慢指针指向头指针,两个指针一起往后移动一步.直到相遇,相遇的地方就是循环的开始(如果相遇,说明是有循环的节点,这时快指针走的路程是慢指针的两倍,快:开始的k距离,和一圈(或者n圈)循…

2.1  Write code to remove duplicates from an unsorted linked list /* Link list node */ struct node { int data; struct node* next; }; void rem_duplicate(node *head){ if(NULL == head) return ; set<int> hash; set.insert(head->data); while(head->n…

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…

Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists: A: a1 → a2 ↘ c1 → c2 → c3 ↗ B: b1 → b2 → b3 begin to intersect at node c1. Notes: If the two linked lists have…

Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists: A: a1 → a2 ↘ c1 → c2 → c3 ↗ B: b1 → b2 → b3 begin to intersect at node c1. 解题思路: 先遍历两个list的长度,然后长的减去短的,之后同时遍历即可…
