What is the output of the following React component?
💡 Model Answer
The component creates a two‑dimensional array called grid with dimensions m x m (default 3x3) and initializes every cell to 0. It then renders a CSS grid container with m columns, each taking an equal fraction of the available width. Inside the container, each cell of the grid array is rendered as a div (or other element) displaying the value 0. Therefore, the visual output is a 3x3 grid of zeros, each cell occupying an equal square area. If m were changed, the grid would adjust accordingly, but the default renders a 3x3 table of zeros.
