import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        while (scanner.hasNext()) {
            int n = scanner.nextInt();
            String[] strs = new String[n];
            for (int i = 0; i < n; i++) {
                strs[i] = scanner.next();
            }

            String regex = scanner.next();
            Pattern pattern = Pattern.compile(regex.toLowerCase());

            for (int i = 0; i < n; i++) {
                Matcher matcher = pattern.matcher(strs[i].toLowerCase());
                if (matcher.find())
                    System.out.println(i + 1 + " " + strs[i]);
            }

        }
    }

}

直接把模式串视为正则表达式
