1. Problem 6: For each language over alphabet $\Sigma=\{a,b\}$, provide two strings that are members and two strings that are not members. 2. a) Language $a^*b^*$: strings with zer

1. Problem statement: Design a Turing machine that accepts strings of the form $0^n1^n2^n$ over the alphabet $\Sigma = \{0,1,2\}$. This means the machine should accept strings that

1. Problem: Write the finite automata corresponding to the regular expression $(a + b)^* ab$. 2. Explanation: The regular expression $(a + b)^* ab$ denotes strings that consist of

1. **Problem statement:** Construct DFAs recognizing languages over alphabet $\{0,1\}$: (a) Strings that begin with $1$ and end with $0$.
