Question

"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 starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length. Ex: The following patterns yield a userScore of 4:

simonPattern: RRGBRYYBGY
userPattern:  RRGBBRYBGY

import java.util.Scanner;

public class SimonSays {
   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      String simonPattern;
      String userPattern;
      int userScore;
      int i;

      userScore = 0;

      simonPattern = scnr.next();
      userPattern = scnr.next();

      /* Your solution goes here */

      System.out.println("userScore: " + userScore);

      return;
   }
}

import java.util.Scanner;

public class SimonSays {

    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        String simonPattern;
        String userPattern;
        int userScore;
        int i;
        userScore = 0;
        simonPattern = scnr.next();
        userPattern = scnr.next();
        for (i = 0; i < simonPattern.length(); ++i) {
            if (simonPattern.charAt(i) != userPattern.charAt(i)) {
                break;
            } else {
                userScore++;
            }
        }
        System.out.println("userScore: " + userScore);
        return;
    }
