题目描述
Polycarp is working on a new operating system called BerOS. He asks you to help with implementation of a file suggestion feature.
There are n files on hard drive and their names are f1,f2,…,fn . Any file name contains between 1 and 8 characters, inclusive. All file names are unique.
The file suggestion feature handles queries, each represented by a string s . For each query s it should count number of files containing s as a substring (i.e. some continuous segment of characters in a file name equals s ) and suggest any such file name.
For example, if file names are "read.me", "hosts", "ops", and "beros.18", and the query is "os", the number of matched files is 2 (two file names contain "os" as a substring) and suggested file name can be either "hosts" or "beros.18".
输入格式
The first line of the input contains integer n ( 1≤n≤10000 ) — the total number of files.
The following n lines contain file names, one per line. The i -th line contains fi — the name of the i -th file. Each file name contains between 1 and 8 characters, inclusive. File names contain only lowercase Latin letters, digits and dot characters ('.'). Any sequence of valid characters can be a file name (for example, in BerOS ".", ".." and "..." are valid file names). All file names are unique.
The following line contains integer q ( 1≤q≤50000 ) — the total number of queries.
The following q lines contain queries s1,s2,…,sq , one per line. Each sj has length between 1 and 8 characters, inclusive. It contains only lowercase Latin letters, digits and dot characters ('.').
输出格式
Print q lines, one per query. The j -th line should contain the response on the j -th query — two values cj and tj , where
- cj is the number of matched files for the j -th query,
- tj is the name of any file matched by the j -th query. If there is no such file, print a single character '-' instead. If there are multiple matched files, print any.
