What is Island traversal?
Island traversal is a grid-based technique used to find connected regions of cells that share a common value, typically 1s in a binary matrix. It combines grid traversal with depth-first or breadth-first search — often with visited tracking — to count islands, measure their size, or analyze their shape.
