Consider the relation r(a, b,c, d) with fds ab -> c, c-> d, d-> a. what is the 3nf status of r? 1. ris in 3nf. 2. ris not in 3nf. it must be deconstructed into r1(a, b,c) with ab-> c and r2(a, b,d) with d-> a. s. r is not in 3nf. it must be deconstructed into r1(a, b,c) with ab-> c, r2(a, b,d) with d-> a and r3(a, b,d) 4. ris not in 3nf but there is no unique deconstruction.

3. (5 points) describe what would be printed by the code below or what error would occur. const char* cstr = "0123456"; const char* ptr = & cstr[4]; cout < < ptr[-1] < < ptr < < endl; 1 4. (5 points) theseus has been trapped in a maze with a minotaur, which is trying to capture him. each round, theseus and the minotaur move through the maze; theseus towards the exit, and the minotaur towards theseus. theseus can move in any of the four cardinal directions, or he can wait for a round to see how the minotaur moves. write code that creates a data type to represent the possible moves that theseus could make.
