给定一个链表,你需要删除那些绝对值相同的节点,对于每个绝对值K,仅保留第一个出现的节点.删除的节点会保留在另一条链表上.简单来说就是去重,去掉绝对值相同的那些.先输出删除后的链表,再输出删除了的链表. 建立结构体节点,包括起始地址addr,下一个地址to,值value.链表数组索引为地址,接下来就是模拟链表的操作了,并且建立一个flag数组标记对应值K是否出现,若出现则flag[k]=addr,未出现则为-1,注意这里不能为0因为地址值存在为0的情况.最后的输出地址前面要补0,如果是链尾的话,-…

题意: 给出一个链表,删除绝对值相同的结点,对于每个绝对值为K的结点,只保留第一次出现的那个.把被移除的结点组成一个新链表,输出删除去重后的链表和新链表. 思路:考察链表的“删除”操作,不难. 代码: #include <cstdio> #include <cstdlib>//abs() ; struct Node{ int data; int curr,next; }LinkList[N],ansList[N]; void printLinkList(int p) { ){ pr…

题意: 输入一个地址和一个正整数N(<=100000),接着输入N行每行包括一个五位数的地址和一个结点的值以及下一个结点的地址.输出除去具有相同绝对值的结点的链表以及被除去的链表(由被除去的结点组成的链表). AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ],val[]; vector<pair<int,int> >ans,a…

今天开个坑,分类整理PAT甲级题目(https://pintia.cn/problem-sets/994805342720868352/problems/type/7)中1051~1100部分.语言是modern C++. 为什么要整理呢,因为我2019年9月要考PAT甲级,虽然是第一次考,虽然只学了数据结构(https://mooc.study.163.com/course/1000033001?tid=2402970002#/info),但我要冲着高分(2019年9月8日更新:满分)去. 下…

1032 Sharing (25分) 回顾了下链表的基本使用,这题就是判断两个链表是否有交叉点. 我最开始的做法就是用cnt[]记录每个节点的入度,发现入度为2的节点即为答案.后来发现这里忽略了两个链表初始节点都是一样的情况,于是这里cnt[]的含义变为每个节点被引用的次数,当一个节点被引用两次就说明被两个链表同时引用.此时又通过了部分测试样例,可是测试样例5始终通过不了.后来偶然翻到一篇博客才恍然大悟,这里的节点可能不止包含两个单词,即可能有多个起点表示多个单词,而题目只是问你给定的两个单词有…

考虑到PAT甲级考试和开学后的XCPC比赛,决定寒假把PAT (Advanced Level) Practice刷完,进度条会在这篇博客下更新.由于主要以记录为主,大体上不会像单篇题解那么详细,但是对问题的思考,代码的简洁性.可读性还是有保障的,欢迎看到的小伙伴和我讨论 2021.1.10 1001 A+B Format (20分) 很久没写题了,没想到卡了半个小时,惭愧.这里是要把结果用逗号分隔成三组,即以千为单位,不足的话则不必要填逗号,我最多只添了一个逗号,要看清题目意思再动笔 #incl…
