Question
### Problem Description In the context of Chapter 7, this exercise involves building a Pushdown Automaton (PDA) that accepts a specific set of strings over the alphabet \(\{a, b, c\}\). The acceptance is determined by the empty stack method. The language of strings that the PDA is designed to accept is defined as follows: \[ \{ a^i b^i c^j a^j \mid i > 0, j > 0 \} \] ### Task 1. **Build a PDA**: Design a Pushdown Automaton that accepts the language characterized by the pattern \(a^i b^i c^j a^j\). 2. **Acceptance Method**: Ensure that the PDA accepts strings by emptying the stack. 3. **Tools and Resources**: It is recommended to utilize JFLAP, a software tool for experimenting with formal languages and automata, to aid in constructing and testing the PDA. ### Explanation - **Notation \(a^i b^i c^j a^j\)**: This notation represents strings where there are \(i\) occurrences of 'a' followed by \(i\) occurrences of 'b', and then \(j\) occurrences of 'c' followed by \(j\) occurrences of 'a'. - **Constraints**: Both \(i\) and \(j\) are greater than 0, implying each segment appears at least once in a valid string. By using JFLAP, you can visually design and simulate the behavior of the PDA to ensure it properly recognizes strings conforming to the specified language pattern.
