[PAT]02-线性结构2 Reversing Linked List (25分) Given a constantKK and a singly linked listLL, you are supposed to reverse the links of everyKK elements onLL. For example, givenLL being 1→2→3→4→5→6, ifK = 3K=3, then you must output 3→2→1→6→5→4; ifK = 4K=4, you...
Linked List Cycle 题目链接 python代码实现: 实现思路: 快慢指针法。定义两个指针:快指针每次走一步;慢指针每次走两步。依次循环下去,如果链表存在环,那么快慢指针一定会有相等的时候。 为了便于理解,你可以想象在操场跑步的两个人,一个快一个慢,那么他们一定会相遇(无论他们的起始点是不是在操场)... ...

定义一个vector<int>listAddress,由所给链表开始地址处开始遍历整个链表,按遍历顺序将各结点地址储存到listAddress中。 按要求对listAddress数组进行翻转,可以利用c语言库里的reverse函数 按格式要求进行结果输出 注意点: (1)题目给出的结点中可能有不在链表中的无效结点 ...
