    Default Check String Pattern in Java

    Hello,

    First I get a number (numbers of string to check) then get the pattern.
    If the string contains the pattern, print Yes otherwise No.

    For example:
    4 quera102

    quEra0012
    qu0erraa12
    sN0Ap12
    qurra00L

    No
    Yes
    No
    No


    I wrote the below code but I get 71 from 100.


    package My;
    import java.util.*;
     
    public class NewMain
    {
     
        public static void main(String[] args) 
        {
            Scanner scanner = new Scanner(System.in);
     
            int n = scanner.nextInt();
     
            String pattern = scanner.next();
     
            String []myString = new String[n];
     
            for (int i = 0; i< n ; i++)
            {
                myString[i] = scanner.next();
            }
            boolean flag = true;
               for (int i = 0; i< n ; i++)
            {
                flag = true;
                for (int j = 0 ; j < myString[i].length(); j++)
                {
                    int indexOf = pattern.indexOf(myString[i].charAt(j));
                    if (indexOf == -1)
                    {
                        flag = false;
                        break;
                    }
                }
                if (flag == false)
                    {
                       System.out.println("No");
                    }
                        else
                    {
               System.out.println("Yes");
     
                    }
            }
     
        }
    }

    I get 71 from 100.
    Does that mean the code misses 29 items?
    Can you print the 29 items that the code misses that should have been detected so we can see where it has the problem?
    If you don't understand my answer, don't ignore it, ask a question.

    My point is 71% from 100%

    We don't have failed examples.

    I attached the output and two conditions in question.

    Sorry, I can not copy anything from an image. Also I do not go to other sites.
    Please copy the items that were not correctly identified and paste them here.
    Without examples of input that was incorrectly identified, I don't know how to work on the problem.

    two conditions in question.
    Any conditions that the code should be testing for needs to be included in the source file as comments so that anyone reading the code knows what the code is trying to do.
    If you don't understand my answer, don't ignore it, ask a question.
