Can you help the police locate the robber?
The robber is hiding in a modern city, where the roads are all at right angles and equally spaced. Imagine the grid lines represent roads. The robber is hiding at a crossroads.
Input coordinates to help the police search and find the robber with the fewest guesses. The interactivity gives you the shortest distance you'd have to travel (along the roads) to reach the robber.
Can you find a reliable strategy for choosing coordinates that will locate the robber in the minimum number of guesses?
