排序,水题因为最后如果一个学生最好的排名有一样的,输出的课程有个优先级A>C>M>E那么按这个优先级顺序进行排序每次排序前先求当前课程的排名然后再与目前最好的排名比较.更新 至于查询,建立id与索引的映射即可. #include <iostream> #include <algorithm> #include <cstdio> #include <cstring> #include <map> using namespace s…

水题,分组排序即可. #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> using namespace std; /* 太水水水... */ +; int cnt1,cnt2,cnt3,cnt4; struct Node{ int id; int tot; int vir; int tal; bool operator<(const Node t…

n转化为b进制的格式,问你该格式是否为回文数字(即正着写和倒着写一样)输出Yes或者No并且输出该格式又是水题... #include <iostream> #include <cstdio> #include <algorithm> #include <cstring> using namespace std; ; int a[maxn]; int n,b; int main() { scanf("%d %d",&n,&…

贪心水题,每次取最短的两个绳子合并,长度缩减成一半 #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <string> #include <map> using namespace std; +; int a[maxn]; int main() { int n; scanf("%d",&am…

三个注意点: 1.给出的n个节点并不一定都在链表中 2.最后一组样例首地址即为-1 3.输出地址的时候一直忘记前面要补0... #include <iostream> #include <algorithm> #include <cstdio> #include <string.h> using namespace std; +; struct Node{ int addr; int val; int to; bool operator<(const…

题意:给出n个人的姓名.性别.ID.分数,让你找出其中哪个妹纸分数最高.哪个汉子分数最低.以及他们的差如果没有妹纸或者汉子,则对应输出Absent,差用NA代替. 就是for一遍找最大最小值,水题 #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <cmath> #include <vector> #defin…
