True or False? (a) If I prove that an algorithm takes O ( n 2 ) worst-case time, then it is possible that it takes O ( n1.9 ) on some inputs. (b) If I prove that an algorithm takes O ( n 3 ) worst-case time, then it is possible that it takes O ( n2.9 ) on all inputs. (c) If I prove that an algorithm takes Θ( n 4 ) worst-case time, then it is possible that it takes O ( n3.9 ) on some inputs. (d) If I prove that an algorithm takes Θ(n 5 ) worst-case time, then it is possible that it takes O ( n4.9 ) on all inputs. (e) An algorithm that takes n3+5n time is always faster than an algorithm that takes O(n3) time.
