FTP, identify these programs that analyze an input sequence and determine its grammatical structure.
One example of this class of programs is the operator-precedence type which has difficulty processing symbols with multiple meanings. Top-down ones include the packrat and the LL algorithm while chart ones include the Earley and the CKY algorithms and are frequently used for natural languages. Handle pruning is a technique used in shift-reduce types of them. Some compilers use a namesake generator, such as GNU Bison, to create one of these for each code. These usually operate on the output of a lexical analyzer and themselves output a tree of tokens. FTP, identify these programs that analyze an input sequence and determine its grammatical structure.
