字符串字串判定 正则表达式

思路

利用正则表达式, 在子序列里插入".*"

import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Main{
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String s = sc.next();
        String seq = sc.next();

        String[] split = seq.split("");

        String deal = String.join(".*", split);

        Pattern p = Pattern.compile(deal);
        Matcher mat = p.matcher(s);

        System.out.println(mat.find()?"Yes":"No");

    }
}
