[程序思路] 先根据地址按顺序读入节点,入栈,当栈里的元素个数等于k时全部出栈,并按出栈顺序保存,最后若栈不为空,则全部出栈并按出栈的稀饭顺序保存,最后输出各节点 注意:输入的节点中有可能存在无用节点需要过滤,这里我使用map映射来实现过滤 [代码实现] #include<bits/stdc++.h> using namespace std; struct node{ int addrest,data,next; }t; int stk[100005]; int main(){ map<…

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…
