There is a database,partychen want you to sort the database’s data in the order from the least up to the greatest element,then do the query: “Which element is i-th by its value?”- with i being a natural number in a range from 1 to N.
It should be able to process quickly queries like this.
The standard input of the problem consists of two parts. At first, a database is written, and then there’s a sequence of queries. The format of database is very simple: in the first line there’s a number , in the next N lines there are numbers of the database one in each line in an arbitrary order. A sequence of queries is written simply as well: in the first line of the sequence a number of queries is written, and in the next lines there are queries one in each line. The query “Which element is i-th by its value?” is coded by the number i.
The output should consist of K lines. In each line there should be an answer to the corresponding query. The answer to the query “i” is an element from the database, which is i-th by its value (in the order from the least up to the greatest element).
5 7 121 123 7 121 3 3 2 5
121 7 123
After we sort the data we get 7 7 121 121 123,so the postion 3 is 121,the postion 2 is 7 and the position 5 is 123 etc.
