Ullman (Compiler Design) Edition 2 Exercise 5.2 Question 3 (Page No. 317)
Suppose that we have a production $A\rightarrow BCD$. Each of the four nonterminals $A, B, C,$ and $D$ have two attributes: $s$ is a synthesized attribute, and $i$ is an inherited attribute. For each of the sets of rules below, tell whether the rules are consistent ... $A.s=D.i,B.i=A.s+C.s,C.i=B.s,$ and $D.i=B.i+C.i.$
