Use Algorithm 1 to find the transitive closures of these relations on {a, b, c, d, e}. a) {(a, c),(b, d),(c, a),(d, b),(e, d)} b) {(b, c),(b, e),(c, e),(d, a),(e, b),(e, c)} c) {(a, b),(a, c),(a, e),(b, a),(b, c),(c, a),(c, b),(d, a),, (e, d)} d) {(a, e),(b, a),(b, d),(c, d),(d, a),(d, c),(e, a),(e, b),, (e, c),(e, e)} | Numerade
