Syntax directed translation

Question

consider the sdts(using synthesized attributes)

s->aB {out "cat"}

s->bA {out "dog"}

B->aBB{out "pig"}

A->bAA{out "cow"}

B->b{out "deer"}

A->a{out "lion"}

the output for aabb is

a)cat pig deer deer b)cat dog pig lion c)cat cow deer lion d)cat deer dog pig

Comments

S --> aB --> aaBB --> aaBb --> aabb

It should be deer deer pig cat, right ? As we are using SDTS with synthesized attributes, we can only implement it by a BUP.
