So I want to develop this Mastermind game, it's quite complete. It works with numbers instead of pegs. Yet I have to tweak it a little bit.
See I want to extend the program to allow repeated numbers in the correct sequence and in the candidate sequences. Instead of being 1234, I want to make it so it can be 1122 for example.
The main difficulty in this case is the calculation of the score
after a guess of the codebreaker.The implementation must also test if the program works properly with repeated numbers in the sequences.
This is al a bit complicated, could you guys lend me a hand?
Code:package practica3;

/*for (int i=0;i<20;i++){//Condition is true so it executes the instructions
int x=generateRandomNumber(9);
System.out.print(x + " ");
}
*/
/* int []s;
int []r;
r=generateRandomSequence(4,8);
s=readSequence(4,8);
printSequence(s);
printSequence(r);
checkSequence(s,r);*/
