A new method for handling the left-recursions for top-down parsing is presented. This method preserves the structure of the parse tree specified by the given grammar. Besides, the parsers written based on this method are usually smaller than the parsers written based on the traditional method....
Left recursion, in the context of Computer Science, refers to a situation in a context-free grammar where a nonterminal symbol can directly or indirectly derive a sentential form that begins with itself. This can lead to difficulties when using a top-down parser, as it may result in an infi...
When we write a go program, for most the cases, we use slices instead of arrays.An array is fixed in size. But slices can be dynamic: the number of elements in a slice can grow dynamically. Keep in mind that slice uses array behind the curtain but slice by itself cannot store any ...
