Safayet Hossain M.Sc student of … answer comment 2 Answers. (c) Indicate what arcs must be added to the digraph for A to get the digraph of the transitive closure, and draw the digraph of the transitive closure. Hence the matrix representation of transitive closure is joining all powers of the matrix representation of R from 1 to |A|. Check transitive To check whether transitive or not, If (a , b ) ∈ R & (b , c ) ∈ R , then (a , c ) ∈ R Here, (1, 2) ∈ R and (2, 1) ∈ R and (1, 1) ∈ R ∴ R is transitive Hence, R is symmetric and transitive but not reflexive Subscribe to our Youtube Channel - https://you.tube/teachoo digraph and (b) find the matrix T of the transitive closure using the digraph implementation of Warshall’s algorithm.
