Answer the homework exercise please Thank you!

Abstract Syntax Trees in Code Write a constructor for the node type of each production SHS+E E E number (5) ---- E_node* NumNode (int val){ } E_node* ParenNode(s_node* 5){ } S_node* PlusNode (S_node* lhs, E_node* rhs){ . } S_node* ENode (E_node* e) { ... } . Exercise: Write code for the AST of 1 +(2+3). Hint: Start from the bottom. The AST for 2 is NumNode(2). What's the AST for 2 + 3? 11 Abstract Syntax Trees in Code Write a constructor for the node type of each production SHS+E E E number (5) ---- E_node* NumNode (int val){ } E_node* ParenNode(s_node* 5){ } S_node* PlusNode (S_node* lhs, E_node* rhs){ . } S_node* ENode (E_node* e) { ... } .
