Consider the following grammar: (1) expr rightarrow term term_tail (2) term tail rightarrow add_op term term_tail | epsilon (3) term rightarrow factor factor_tail (4) factor_tail rightarrow mult_op factor factor_tail | epsilon (5) factor rightarrow (expr) |id| literal (6) add_op rightarrow (expr) |id| literal (7) mult_op rightarrow *|/We have the input (18*a4) * bc for parsing (syntactical analysis). Do derivation and collect all the grammar rules applied in the derivation to build (draw) a syntax tree for this input. Do lexical analysis first
