简单并带有错误的环形单链表检测代码

LinkedList* IsCyclicLinkedList (LinkedList* pHead){LinkedList* pCur;LinkedList* pStart;while (pCur != NULL){for ( ; ; ){if (pStart == pCur->next)return pStart;pStart = pStart->next;}pCur = pCur->next;}return pStart;} 

 

我修改后如下：

LinkedList* IsCyclicLinkedList (LinkedList* pHead){LinkedList* pCur = pHead;LinkedList* pStart = pHead;while (pCur != NULL){if (pStart == pCur->next)return pStart;/*pStart = pStart->next;*/pCur = pCur->next;}return pStart;}
