Solution: Spiral Matrix II

Explore how to generate an n×n matrix filled with numbers from 1 to n² following a spiral pattern. Understand the step-by-step traversal of matrix layers in four directions to complete the pattern efficiently with O(n²) time and constant space complexity.

We'll cover the following...

Statement

Given a positive integer n, create an n×nn \times n, matrix where the elements are sequential integers from 11 to n2n^2, arranged in a spiral pattern.

Constraints:

  • 1 ≤\leqn ≤\leq2020 ...
