Deterministic Automated Function

[Jake S.]

Problem: Create a DFA in which the bit string has a third to last bit that is a 1.

 

Example of a bit string that works: 1010110100 

 

I was able to create a DFA in which the third digit from the front is a 1.

 

 

 

How would I create one in which the third to last bit is a 1? Please include a drawing/diagram 

Thank you
