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

Given Code in JAVA:

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();

   //Insert your solution 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("User score is " + userScore);
    }
}
