LL parser separated by '+'. In a regular expression form T ('+' T)*. So the rule could be rewritten as Now there is no left recursion and no conflicts on either of the rules. However, not all CFGs have an equivalent LL(k)-grammar, e.g.: It can be shown that there does not exist any LL(k)-grammar accepting the language generated by this grammar. LL parser In computer science, an LL parser is a top-down parser for a subset of context-free languages. It parses the input from Left to right, performing Leftmost derivation of the sentence. An LL parser is called an LL("k") parser if
