Transitive closure

Transitive closure is a way to identify all the possible connections within a set of items linked by relations. Imagine a network of roads connecting cities; if city A connects to city B, and city B connects to city C, then the transitive closure helps determine that city A is also connected to city C indirectly. It essentially finds all the reachable points in a system, making sure you know all the paths, direct or indirect, between elements. This concept is useful in areas like computer science, social networks, and logistics to understand the full extent of connectivity.
