Suppose m is passed as 3, then you have to display an m x m (3x3) matrix in the UI. You can use grid, flexbox, or any other method.

To render a 3x3 matrix in the UI, create a container element and apply CSS Grid. Set display: grid; and grid-template-columns: repeat(3, 1fr); to create three equal columns. Inside the container, generate nine child elements (e.g., divs) that represent each cell. You can use a loop in JavaScript or a templating engine to create the cells. Each cell can be styled with borders or background colors to make the grid visible. The complexity is O(9) for rendering, which is effectively constant for a fixed size. If you need to support dynamic sizes, replace the hard‑coded 3 with a variable m and use repeat(m, 1fr) for both rows and columns. This approach scales linearly with the number of cells (O(m²)).
