**Math Quiz:**

Write a Python program (`math_quiz.py`) that displays simple arithmetic problems and asks users for the answer. The program has two functions:

- **Create the following constants:**
  - `RANDOM_MAX_NUM`: Initialize with 20 (upper range for randomly selecting two numbers for math problems).
  - `RANDOM_MAX_OP`: Initialize with 4 (upper range for randomly selecting a number between 1 and 4).

**main()**
- Initializes counters for score (number correct) and number of tries.
- Calls `fMathQuiz()`.
- Uses the Boolean value returned by `fMathQuiz()` to see if the user was right or wrong.
- Updates user’s score and the number of attempts appropriately.
- Asks user if they want to play again (y or n).
  - Validate user’s response. Ask again if what the user entered is not y or n.
  - If the user entered y, loop back for another math problem.
  - If the user entered n, display "Your score: N correct in M attempts." and quit the program.

**fMathQuiz()**
- Chooses two different random integers between 1 and `RANDOM_MAX_NUM` (inclusive).
- Randomly picks one of the following four arithmetic operators: +, -, *, / (use `RANDOM_MAX_OP`).
- Computes the correct answer for the chosen numbers and operator, but does not display it.
- Displays the arithmetic problem using the two numbers and the operator.
  - Examples:
    - `19 / 3`
    - `5 - 3`
    - `14 * 2`
- Waits for the user to enter an answer.
  - If the user’s answer is correct, print “Correct!” and return True.
  - If the user’s answer is wrong, print “Wrong! Correct answer is:” with the correct answer, and return False.
