How do you reduce in parsing table for expression grammar in compiler course. i under stand the shift action but unable to understand reduce action please help?
In a parsing table for an expression grammar, the reduce action is used to combine grammar rules to reduce a portion of the input string into a non-terminal symbol. When the parser encounters a reduce action in the parsing table, it replaces a set of symbols on the top of the stack with the non-terminal symbol that corresponds to the grammar rule being applied. This helps in simplifying the input string and moving towards the final goal of parsing the entire input.

How do you show that a grammar is LALR but not SLR?
To show that a grammar is LALR but not SLR, you can construct a parsing table for the grammar and demonstrate that there are conflicts present in the SLR parsing table that are resolved in the LALR parsing table. Specifically, LALR parsers have larger look-ahead sets than SLR parsers which can resolve these conflicts. In other words, LALR parsers are able to distinguish between more parser states compared to SLR parsers, allowing them to handle more complex grammars.
What would be the most efficient dining table design which could fit the most amount of food?
The most efficient design would be a buffet style setup where all the food is placed next to each other to maximize space. This type of set up is usually done when entertaining a large number of guests.
