See if you can answer this fish riddle. Imagine you’re a cargo driver who has agreed to transport several tanks of a critically endangered fish species to a new aquarium. Unfortunately, as you’re passing through shark-infested waters, the boat is battered by a fierce storm, tossing your cargo overboard. There’s one rescue sub at your disposal, but you only have enough fuel for one trip to the ocean floor. Before deciding to rescue them, you need to know where the tanks are so you can gather them all in one quick pass. Not a single fish can be lost.
