We define B is a Divisor of one number A if A is divisible by B. So, the divisors of 12 are 1, 2, 3, 4, 6, 12. So, 12 has 6 divisors in total.Now you have to order all the integers from 1

Description有一家旅馆，共有M个房间，编号为1到M。某天，来了N个客人（编号为1到N）住宿，每个人当然是住在这M个房间中的一个。问题：求出每个房间中的客人的编号？Input多组数据。每组数据的第一行输入N M （1 <= N <= 1000000, 1 <= M <= 10000）第二行有N个数，其中第i个数表示第i个客人所住的房间的编号

1：给出n个字符串，输出每个字符串是第几个出现的字符串？多组数据2：对每组数据，第一行输入n表示接下来有n个字符串 1 接下来的n行，每行输入一个非空的且长度最多为10的仅由大写字母组成的字符串3：输出共n行，对每一行的字符串，输出其是第几个出现的字符串。解题思路：直接map//mp.clear();#include#include#include#includeu
