## Round 1 - Coding / OOD ## Problem Design an ASCII art rendering system. Support rendering rectangles, triangles, and text banners to a 2D character canvas. Each shape is a separate class. The canvas can combine multiple shapes and print the result. ```python class Canvas: def __init__(self, width: int, height: int, fill: str = " "): ... def draw(self, shape: 'Shape', x: int, y: int) -> None: ... def render(self) -> str: ... class Rectangle: def __init__(self, width: int, height: int, char: str = "*"): def pixels(self) -> list[tuple[int,int]]: ... class TextBanner: def __init__(self, text: str): def pixels(self) -> list[tuple[int,int,str]]: ... ``` ## Example ``` c = Canvas(10, 5) c.draw(Rectangle(4, 3, "#"), x=1, y=1) c.render() # ---------- # | | # | #### | # | #### | # | #### | # ---------- ``` ## Follow-ups 1. How do you handle overlapping shapes — which one takes priority and why? 2. How would you add a `Triangle` shape that fills using Bresenham's line algorithm? 3. How would you support layering (z-index) so shapes can be explicitly ordered? 4. How would you serialize the canvas state to a JSON file and restore it?
