 2. 请给出 DFA 化简中 State Elimination Technique 的复杂度的 tight bound, 要有明确的推理过程
 
-3. A marble is dropped at A and B. Levers x1, x2 and x3 cause the marble tofall either to the left or to the right. Whenever a marble encounters a lever, it causes the lever to reverse after the marble passes, so the next marble will take the opposite branch. The game wins when there is a marble falls through C. The levers are all initialized to the left. Model this toy by a DFA.
