STEPS

1. Ask the user for a secret number
2. Store the SECRET number
3. Make a computer GUESS, within a range of MIN and MAX

• Create the guess randomly or using a mid-point between min/max

4. Ask, if the GUESS is correct

• IF yes, THEN send message and exit the game
• IF no, THEN ask a follow up question, for HIGH or LOW

5. Ask, Is SECRET number HIGHER or LOWER

• IF HIGHER
  • Update the MIN to the GUESS + 1
• IF LOWER
  • Update the MAX to the GUESS - 1

6. Loop back to Step.3
