Dfa Language
1. **Problem Statement:** Identify the language recognized by the given DFA with states 0 to 7, initial state 0, and terminal states 5, 6, and 7.
2. **Understanding the DFA:** The DFA transitions are:
- From 0: 0\to1, 1\to2
- From 1: 0\to3, 1\to4
- From 2: 0\to4
- From 3: 0\to6, 1\to5
- From 4: 0\to5
- From 5: 0 or 1\to7
- From 6: 0 or 1\to6 (loop)
- 7 is terminal with no outgoing edges.
3. **Terminal states:** 5, 6, 7
4. **Analyzing paths to terminal states:**
- To reach 6: must go 0 (from 0 to 1), 0 (1 to 3), 0 (3 to 6), then stay in 6 with any input.
- To reach 5: can go 0,1,1 (0 to 1 to 4 to 5) or 0,0,1 (0 to 1 to 3 to 5) or 1,0,0 (0 to 2 to 4 to 5).
- To reach 7: from 5 with any input 0 or 1.
5. **Language description:**
- Strings starting with 0, then 0, then 0, followed by any combination of 0s and 1s (loop in 6).
- Strings that reach 5 by paths described, then optionally followed by 0 or 1 to reach 7.
6. **Formalizing:**
- The language includes strings over {0,1} that:
- Start with 000 and then any string (for state 6), or
- Start with 001 or 011 or 100 and then possibly one more symbol (for states 5 and 7).
7. **Summary:** The language recognized is all strings over {0,1} that lead from 0 to terminal states 5, 6, or 7 following the described transitions.
**Final answer:** The language recognized by the DFA consists of all strings over {0,1} that either:
- Contain the prefix 000 followed by any string (looping in state 6), or
- Contain prefixes 001, 011, or 100 leading to state 5, optionally followed by one more symbol to reach state 7.
