By using our site, you To gain better understanding about Construction of DFA. First, we define our dfa variable and . How to deal with old-school administrators not understanding my methods? Agree Since, regular languages are closed under complement, we can first design a DFA that accept strings that surely end in 101. Note carefully that a symmetry of 0's and 1's is maintained. 0 and 1 are valid symbols. Solution: The FA with double 1 is as follows: It should be immediately followed by double 0. Since in DFA, there is no concept of memory, therefore we can only check for one character at a time, beginning with the 0th character.
