Simon says is a memory game where "simon" outputs a sequence of 10 characters (r, g, b, y) and the user must repeat the sequence. create a for loop that compares the two strings. for each match, add one point to user_score. upon a mismatch, end the game. sample output with inputs: 'rrgbryybgy' 'rrgbbrybgy'

// Here is code in java.

import java.util.*;

// class definition

class Solution

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // create two string and initialize them

       String simon="RRGBRYYBGY";

       String user="RRGBBRYBGY";

       // variable to count score

       int user_score=0;

       // count the score of both strings

       for(int i=0;i<10;i++)

       {

           if(simon.charAt(i)==user.charAt(i))

           user_score++;

// if there is mismatch, loop breaks

           else

           break;

       }

       // print the score

   System.out.println("user score:"+user_score);

   }catch(Exception ex){

       return;}

}

}

Explanation:

Create two string variables and initialize first with simon sequence and second  with user sequence. Create a variable "user_score" to count the score of memory  game.In the for loop, check each character of first string with Corresponding character of second string.If there is match then add 1 to user_score and if  mismatch break the loop.Then print the user_score.

Output:

user score:4

because they are scammers. our phones tells us when there are known scammers calling just so we can be informed. so basically they want to scam you. lol
