Matrix Traversal

Matrix traversal involves visiting all elements of a 2D array in a specific order. Common patterns include row-major, column-major, diagonal, and spiral traversal. These techniques are essential for image processing, game boards, and grid-based problems.

Use Cases

  • Image processing and pixel manipulation
  • Solving grid-based puzzles and game board traversals
  • Converting between matrix representations and flat arrays
