203题是在链表中删除一个固定的值,83题是在链表中删除重复的数值,但要保留一个:82也是删除重复的数值,但重复的都删除,不保留. 比如[1.2.2.3],83题要求的结果是[1.2.3],82题要求的结果是[1,3]. 这种题用递归去做比较方便思考,特别是这种重复的数值.递归就是只遍历当前的节点的情况,之前的不用管,之后的以当前节点为出发点思考问题. 203. Remove Linked List Elements class Solution { public: ListNode* remo…

Remove Duplicates from Sorted List 本题收获: 指针: 不管什么指针在定义是就初始化:ListNode *head = NULL; 如果给head指针赋值为第一个node节点数,则不需要开辟空间(的语句),直接:head = node; 如果另外赋值,需要开辟内存. 总之就是指针既要开辟内存(定义)又要赋值,只定义没有赋值的指针时野指针,危害很大.   指针在删除不用时,删除后,需要让指针指向NULL.    delete p_t;              …
