    //Password Validator
    //Write a program that checks if a given password is valid. Password rules are:
    // 6 – 10 characters (inclusive);
    // Consists only of letters and digits;
    // Have at least 2 digits.
    //If a password is valid, print "Password is valid". If it is not valid, for every unfulfilled rule print a message:
    // "Password must be between 6 and 10 characters";
    // "Password must consist only of letters and digits";
    // "Password must have at least 2 digits"
    //Examples
    //Input
    //logIn
    // Output:
    // Password must be between 6 and 10 characters
    //Password must have at least 2 digits
    //Input:
    //MyPass123
    // Output:
    // Password is valid
    //Input
    //Pa$s$s
    // Output
    // Output:
    // Password must consist only of letters and digits
    //Password must have at least 2 digits
    //
    //Hints
    //Write a method for each rule.
