Please help me with this homework problem, thanks!

Consider the grammar: S + ABC A + A A C A + E B (1) (2) (3) B + dB Ac (5) (6) (7) B + E C + c (8) where S, A, B, and are non-terminals, S is the start variable, and a, b, c, and d are the terminals. 1. Compute the following for FIRST sets: (a) [5pt] What are the initialized FIRST sets after applying rules I and II? (b) (5pt] Do one pass on the grammar rules in the order in which they are listed as follows. For each grammar rules, apply FIRST set rule III, then apply FIRST set rule IV then apply FIRST set rule V. Show the resulting FIRST sets after this one pass. Show the final result of the computation of the FIRST sets
