leetcode括号生成python leetcode打算开始在leetcode上刷题了嗯。希望不要因为各种各样的原因半途而废…… 2015.3.28在这里贴一下写过的题解和思路。长期更新。 #19 Remove Nth Node From End of List Given a linked list, remove the nth node from the end of list and return its head. For example, Given linked list: 1->2->3->4->5, and n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Given n will always be valid. Try to do this in one pass.大体上来说就是删除链表中倒数第n个元素，并没有任何难度。这种程度的题也不管你内存回收什么的所以说随便写就好了。唯一要注意的地方是n等于链表长度的
