今天的上机考试虽然有实时的Ranklist，但上面的排名只是根据完成的题数排序，没有考虑每题的分值，所以并不是最后的排名。给定录取分数线，请你写程序找出最后通过分数线的考生，并将他们的成绩按降序打印。Input测试输入包含若干场考试的信息。每场考试信息的第1行给出考生人数N ( 0 以下N行，每行给出一名考生的准考证号（长度不超过20的字符串）、该生解决的题目总数m、以

/*题意：给n个正整数，求他们的中位数，它们的大小小于2^32 - 1（就因为没仔细思考这句话，wa到怀疑人生）思路：排序分奇偶求中位数即可，但是要避免大数相加溢出。*/#include #include #define N 250005using namespace std;int a[N];int main(){ int n; while (~scanf("%d"

已知一个序列，输出它的不重复全排列思路1.stl应用：next_permutation函数对数组输出全排列，原理每次改变当前字符串变为，大小恰好原来大一阶的序列。若已为最大序列，返回0。说明：next_permutation，重新排列范围内的元素[第一，最后一个）返回按照字典序排列的下一个值较大的组合。返回值：如果有一个更高的排列，它重新排列元素，并返回true；如果这是不可能
