Problem A
ls
You are implementing an operating system, and now need to write a program to list files in a directory: “ls”. You want the user to be able to list only files that match a given pattern that can include wildcards (*), for example *.c. A wildcard matches zero or more characters of any kind.
Input
The first line contains a string $P$, containing $1$–$100$ characters ’a’–’z’, ’*’ and ’.’. This is the pattern. The second line contains an integer $N$, $1 \leq N \leq 100$, which is the number of files in the directory. Then follow $N$ lines containing the names of the files in the directory. Each line is a string containing $1$–$100$ characters ’a’–’z’ and ’.’.
Output
The output shall consist of the filenames that match the pattern, $P$, each on its own line, in the same order that they were given as input.
