ParseTree
A parse tree, also called a parsetree, is a tree data structure that represents the syntactic structure of a sequence of tokens according to a formal grammar. The root is the start symbol, internal nodes are nonterminal symbols, and the leaves are terminal symbols or tokens. The tree encodes how the input can be derived step by step by applying the grammar’s productions.
In computing, a parse tree is produced by a parser during the syntax analysis phase. It provides
Parse trees are distinct from abstract syntax trees (ASTs). A parse tree preserves all details of the
Constructing a parse tree depends on the parsing strategy, such as top-down parsers (LL) or bottom-up parsers
Applications include compilers, interpreters, language tooling, static analysis, and data transformation. For example, in an expression
