Here is a computer science problem. Suppose we organize content by toxicity level: a range of toxicity values such as [0, 0.25), [0.25, 0.5), [0.5, 0.75), and [0.75, 1]. Each element in a given toxicity level is considered equally important for moderation. Now, Design a constant-time data structure for storing and retrieving content by toxicity level for a constant number of toxicity levelsthere are 4 toxicity levels in the above example.
