Do lexical analysis and then draw a syntax tree according to the above grammar for each of the following expressions:

Consider the following LL(1) grammar ()expr term term tail (2)term tail add op term term tail factor factor Tai (5)factor tail mult op factor factor tail (7)factor (expr) (8) number (9) identifier (10)add op (11) (12)mult op (3) Do lexical analysis and then draw a syntax tree according to the above grammar for each of the following expressions: (x1 y 123)*123, x1 y123*123, y123 123 x1, x1 (y123*123). First work on how the grammar rules derive these expressions, and then collect grammar rules used in the derivation for each expression to build a syntax tree for it
