  • $\begingroup$ No. Your machine accepts ababab. Well, actually it works if the aabb don't have to be together. But usually this question means they have to be all together in a row, so ababab doesn't count. $\endgroup$

Have 5 states S, Sa, Saa, Saab, Saabb. Move to a state Sxxx after you parsed the first characters xxx of aabb, except you stay in the accepting state Saabb no matter what the input once you reached it.

S:     a->Sa,    b->S.
Sa:    a->Saa,   b->S.
Saa:   a->Saa,   b->Saab.
Saab:  a->Sa,    b->Saabb.
Saabb: a->Saabb, b->Saabb.

This automaton only accepts strings that START with aabb. You also need to accept strings such as baabb, bababaabbabab, aabaabb, etc.

    $\begingroup$ It accepts also $baabb$, $bbaabb$ etc. The actual problem is it accepts non-consecutive $aabb$ $\endgroup$
