Let R = {(1, 2), (2, 3), (3, 1)} and A = {1, 2, 3} find the reflexive, symmetric and transitive closure of R using composition of relation R.
Show answer outline
The reflexive closure adds (1,1), (2,2), (3,3); symmetric closure adds (2,1), (3,2), (1,3); transitive closure adds (1,3), (2,2), (3,1).

Use Warshall's algorithm to find the transitive closure of the following relation on the set A = {1, 2, 3}. R = {(1, 2), (2, 3), (3, 1)}
Show answer outline
Warshall's algorithm iteratively adds paths to find the transitive closure.
