LL parser

An LL parser is a type of computer program used to analyze and understand sentences or code by reading from left to right and building a structure called a parse tree. It uses a set of rules to predict what comes next, helping to determine if the input follows a specific grammar or language. This process is common in compilers that translate programming languages, ensuring that code is correctly structured. Essentially, the LL parser systematically checks input sequences against grammar rules, making sure they are valid and correctly formed.
