## Passes:
-
- First Pass: Creates the symbol tables and adds all the elements of the program to the symbol table. The first step is creating the basic table symbol, which is the parent(root) of the symbol table structure(which forms a tree-like structure). Classes for Object, int, bool and str are added to this symbol table. This table contains the global declarations. At each level of scope, we create a symbol table which points to the parent symbol table. Variables, functions and classes are added to the appropriate symbol table according to the scope.
- Second Pass: At each node of the abstract syntax tree, the types are identified and populated.
## Recovery:
-
## Challenges:
-
- Nested structures were a challenge. A function inside a function needs to handle variable references as well as ensure function calls have appropriate scope.
## Improvements:
- Added more tests to rigorously check program flow and indentation.

* The rules provided below parse expressions of the form <INT> + <INT> + ...
* You can re-use these rules or edit them as you wish. The start rule
* should return a node of type Program.
*
* Tips: Production rules are usually followed by action code that will be
* copied to the generated parser to be executed immediately after a reduce
* operation; that is, when a production rule has been matched. You can name
* a nonterminal or terminal symbol in a production rule using the colon
* notation, e.g. expr_stmt ::= expr:e, to get the AST node for the matched
* expression. In the action code, `e` will be a variable of whatever type
* has been declared for the corresponding nonterminal, such as `Expr`.
* Therefore, you can construct an AST Node of type `ExprStmt` with `e` in the
* constructor: `new ExprStmt(exleft, exright, e)`
*
* The variables `exleft` and `exright` are automatically generated by CUP
* and contain Location objects for the start and end of the expression `e`.
* You can collect start and line number info for AST nodes by taking the
* location of the left end of the leftmost symbol in a rule and the
* location of the right end of the rightmost symbol. The auto-generated
* variables have names `<sym>xleft` and `<sym>xright`, where <sym> is the
* name given to the symbol using the colon notation.
*
* When you have nonterminals that are lists of things, e.g. List<Stmt> or
* List<Declaration>, it is helpful to get the leftmost and rightmost
* source location from within this list; we have provided some utility
* functions below to do just that.

* The idea is that a phase of the analysis is encapsulated in a class

* analyze method for each concrete Node class that needs something

* The effect is that anode.dispatch(anAnalyzer) executes the method
* anAnalyzer.analyze that is appropriate to aNode's dynamic type.
* As a result each NodeAnalyzer subtype encapsulates all
* implementations of a particular action on Nodes. Thus, it inverts
