Reddit Senior Android Developer interview questions

The problem involves processing a 2D array representing an image, where each pixel is either a `0` or `1`. The array may contain one or more rectangular regions of `0`s surrounded by `1`s. The tasks are: 1. **Identify Rectangles**: Write a function that detects all rectangles of `0`s in the 2D array, returning the coordinates of the top-left and bottom-right corners for each rectangle. 2. **Handle Multiple Rectangles**: Adapt the solution to correctly identify and manage multiple separate rectangles within the image. 3. **Check Point Inside Rectangles**: Implement functionality to determine if a given point is inside any of the detected rectangles.
