Jan 10, 2025 · Spiral Matrix Traversing a Matrix in Spiral Order Traversing a matrix in spiral order is a common problem in programming, where the goal is to extract all elements of a matrix following a specific pattern. If we directly copy elements within the matrix, it would cause data loss. Can you solve this real interview question? Spiral Matrix - Given an m x n matrix, return all elements of the matrix in spiral order. This center-point can be at the coordinates, or it could be at any arbitrary point on the 2D plane. The exercise is a good illustration of how ranges work in Python. /* An integer matrix of size R*C is passed as input.
