Cho các văn phạm:
a) G = ( Σ , Δ , S, R ) với tập quy tắc sinh
R = { S → ABC, AB→ iADj, Dij→ iDj, DiC→ BiC, iB→ Bi, AB→ ε, C→ ε } với i, j ∈ {a, b}.
b) G = < Σ , Δ , S, R > với tập quy tắc sinh: R = {S → SS, S → aSb, S → bSa, S → ab, S → ba}.
c) G = < Σ , Δ , S, R > với tập quy tắc sinh: R = {S → aS, S → a | với a ∈ Σ = {a1, a2, …an}}.

The reset circuit used on the four 3-bit counters analyzed in this activity reset the counts to zero (000). it makes sense for the up-counters to start at zero (000), but the down-counters should start at seven (111). what would you need to change so that the 3-bit binary down counter with j/k flip-flops you just created would reset to seven (111)?
