NFA Solved Examples | How to construct NFA

      Example-1:Design the NFA transition diagram for transition table as given below

Present State	Next State
	Input 0	Input 1
à q0	{q0,q1}	{q0,q2}
q1	{q3}	-
q2	{q2,q3}	{q3}
*q3	{q3}	{q3}

Here the NFA is M= ( {q0,q1, q2, q3},{0,1}, δ , q0, {q3})

Example-02: Design the NFA transition diagram M= ( {q₀,q₁, q₂ }_, δ , q_1, {q₃}) ,Where δ is given by

δ( q₁ , 0)= {q₂,q₃}       ,δ (q₁,1)= {q₁}

δ( q₂, 0)= {q_1,q₂}        ,δ (q₂,1)= ∅    

                        δ( q₃, 0)= {q₂}            ,δ (q₃,1)= {q₁,q₂}

    Example-03: Construct a NFA for a language which accepts all  the strings in which third symbol from right end is always ‘a’
    Example-04: Construct a NFA accepting all the strings ending with 01 over ∑={0,1}

    Example-05: Construct a NFA to accept strings whichend with ‘aa’ over ∑={a,b}
    Example-06: Construct a NFA to accept strings witheither two consecutive 0’s or twoconsecutive 1’s over ∑={0,1}

    Example-07: Construct a NFA to accept language L={w|w contain an even number of 0’s or exactly two 1’s} over ∑={0,1}  

    Example-08: Construct a NFA to accept language L={w ∈ {0,1} } w contains substring 0101
