Here we do 5 more intermediate examples of context-free grammars. In general, I give some techniques to analyze the structure of the given language further, such as decomposing the language into a concatenation, or nesting pairs. I also give examples of where we have to analyze the structure of what the strings look like in the language, and break up the CFG into cases which can be handled separately.
Timeline:
0:00 - Intro
0:15 - Example 1: Nested Pairs
2:45 - Example 2: Concatenated Pairs
4:58 - Example 3: Non-palindromes over {0, 1}
8:29 - Example 4: Complement of {0^n 1^n 2^n : n at least 0}
15:26 - Example 5: {a^i b^j c^k : i is at most j + k}
