错误代码：
class Solution { public: ListNode* deleteDuplication(ListNode* pHead) { if(pHead == NULL) return NULL; if(pHead->next == NULL) return pHead; ListNode* current = NULL; if(pHead->val == pHead->next->val){ current = pHead->next->next; while(current->val == pHead->val && current != NULL) current = current->next; return deleteDuplication(current); } else{ current = pHead->next; pHead->next = deleteDuplication(current); } return pHead; } };
正确代码：
class Solution { public: ListNode* deleteDuplication(ListNode* pHead) { if(pHead == NULL) return NULL; if(pHead->next==NULL) return pHead; ListNode* current = NULL; if(pHead->val == pHead->next->val){ current = pHead->next->next; while(current != NULL && current->val == pHead->val) current = current->next; return deleteDuplication(current); } else{ current = pHead->next; pHead->next = deleteDuplication(current); //return pHead; } return pHead; } };
可以看到不同点只是把current->val == pHead->val和current != NULL换了一下位置
错误的代码报错报的是：段错误:您的程序发生段错误，可能是数组越界，堆栈溢出（比如，递归调用层数太多）等情况引起
