Web2. Construct Context-free Grammar for integers. Integer can begin with + or - and after that we have non-empty string of digits. Integer must not contain unnecessary leading zeros and zero should not be preceded by + or -. For example: 0; 123; -15; +9999 are correct, but +0; 01; +-3; +09; + are incorrect. I have something like this: WebMar 28, 2024 · For the language given, you need the number of $a$'s to match up with the number of $b$'s. Notice that the strategy used to find a CFG for the language is to make sure that whenever we introduce an $a$, that we also introduce a $b$ at the same time. By doing this, we make sure that the number of $a$'s and $b$'s are equal. pink dishwasher tablets
