How do you find the game algorithm?
Divide and Conquer Algorithm (Guessing Game) Steps:
- Add the Highest Range + Lowest range – 1 = Possible Guesses.
- Divide Possible Guesses by 2 Round Up (your guess), ask is this your number?
- If your guess is to low: the Lowest Range = your guess +1.
- If your guess is to high:
- If your guess isn’t to low or to high:
