Island Detection in Binary Matrices Using Graph Traversal
Given a rectangular binary matrix representing a geographical map where character '1' indicates landmass and '0' represents water, the computational task is to enumerate distinct islands. An island forms when land cells connect horizontally or vertically; diagonal adjacency does not constitute valid connectivity. The grid periphery is assumed t ...
