Grokking the Coding Interview Patterns in Go

Solution: Spiral Matrix II

Explore how to create an n by n matrix filled with numbers in a spiral order by systematically iterating through matrix layers. Understand the step-by-step layer traversal in four directions and apply this method to solve complex matrix problems efficiently in coding interviews.

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 ...
