Construct a DFSA to accept each of the following languages. 1. (xe fa,b)* | x ends with aaba) 2. (xe 10,1)* | x does not contain 0011 as a substring) 3. (x in (0,1)* each 0 in x is immediately preceded and immediately followed by a 1). If x does not contain a 0, then it satisfies the condition. (xe (0,1)* | x corresponds to the binary encoding of a positive integer that is divisible by 73. Leading zeros are allowed. 4
