由于最近学的是线性结构,且因数组需开辟的空间太大.因此这里用的是纯链表实现的这个链表翻转. Given a constant K and a singly linked list L, you are supposed to reverse the links of every K elements on L. For example, given L being 1→2→3→4→5→6, if K = 3, then you must output 3→2→1→6→5→4; if K = 4,…

题意说的很清楚了,这种题的话,做的时候最好就是在纸上自己亲手模拟一下,清楚一下各个指针的情况, 这样写的时候就很清楚各个指针变量保存的是什么值. PS:一次AC哈哈,所以说自己动手在纸上画画还是很有好处的~ #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <cmath> #include <queue> us…

题意: 每k个元素反转链表,不足k个就不反转.如原链表为1→2→3→4→5→6,k=3,则反转后的链表为3→2→1→6→5→4:若k=4,则反转后的链表为4→3→2→1→5→6. 思路: 这题会比较烦,写代码前一定要现在纸上理清思路,写出关键代码,不然出了错再改来改去真的很浪费时间,要是考试的话估计心态就蹦了.本题是比较经典的“反转链表(指反转整条链表)”的升级版,但做法是一样的.我们可以把“反转”这一动作单独抽象成一个函数,然后遍历链表,每遍历k个结点(假设是pi...pj),就把pi...p…

题意: 输入链表头结点的地址(五位的字符串)和两个正整数N和K(N<=100000,K<=N),接着输入N行数据,每行包括结点的地址,结点的数据和下一个结点的地址.输出每K个结点局部反转的链表. trick: 测试点6包含一些不在起点这条链表上的结点. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; map<string,pair<i…
