This approach involves iteratively filling the matrix in a spiral pattern while maintaining boundary limits. We initialize four boundaries: top, bottom, left, and right. Starting with top as 0 and so on, we fill the elements from 1 to n² within these boundaries:

• We move from left to right along the top boundary, incrementing the top boundary after completion.
• We move from top to bottom along the right boundary, decrementing the right boundary.
• We then move from right to left along the bottom boundary, decrementing the bottom boundary.
• Finally, we move from bottom to top along the left boundary, incrementing the left boundary.

This process repeats until all numbers are placed in the matrix.
