Grokking the Coding Interview Patterns in Go

Solution: Spiral Matrix

Explore the spiral matrix traversal algorithm that navigates through an m by n matrix in a cyclical pattern. Understand directional control, boundary adjustments, and iteration steps to collect elements in spiral order. This lesson helps you implement an efficient solution with O(m×n) time complexity and constant space usage, essential for matrix problem-solving in coding interviews.

We'll cover the following...

Statement

Given an m×nm\times n matrix, return an array containing the matrix elements in spiral order, starting from the top-left cell.

Constraints:

  • 1≤1\leq matrix.length ≤10\leq 10
  • 1≤1\leq matrix[i].length ≤10\leq 10
