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:
This process repeats until all numbers are placed in the matrix.
Time Complexity: O(n^2), as we iterate through every cell of the matrix.
Space Complexity: O(1) for in-place modification, excluding the space required for the output matrix.
1var generateMatrix = function(n) {
2 const matrix = Array.from({ length: n }, () => Array(n).This JavaScript function employs an array initialization with nested loops to facilitate incremental filling based on boundary shifts. The code provides a complete spiral matrix as output once all numbers are allocated.
