1. What were the scores?
2. What strategy did the low scorers use?
3. Which ship should you choose first? (The one in the middle tells you which half of the
line the chosen ship must be in.) Which location would you choose next? (Again the best
strategy is always to choose the middle ship of the section that must have the selected
ship.)
4. If this strategy is applied how many shots will it take to find a ship? (Five at most).
This method is called ‘binary search’, because it divides the problem into two parts.
