/*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".
