Parse tree is the graphical representation of symbol. The symbol can be terminal or non-terminal. In parsing, the string is derived using the start symbol. The root of the parse tree is that start symbol. It is the graphical representation of symbol that can be terminals or non-terminals. Parse tree follows the precedence of operators.
