- Nested structures were a challenge. A function inside a function/class needs us to build correct scoping as well as dealing with dependencies. - Nested structures were a challenge. A function inside a function/class needs us to build correct scoping as well as dealing with dependencies.

Instead, we defined certain set of variables in the beginning of the student contributed test programs, and then used the same variables throughout the programs to cover various bad and good scenarious.
- Another challenge was to come up with good test cases to have a broader cover. Our approach to this issue was investigating Type Checking rules and writing adverse code to those rules to see if our analyzer can make correct inferences. - Another challenge was to come up with good test cases to have a broader cover. Our approach to this issue was investigating Type Checking rules and writing adverse code to those rules to see if our analyzer can make correct inferences.
- Syncornizing the implementation was extra challening for pa3 compared to previous ones. Reason was the flexbility and freedom of the code generation step. Our RISC-V code did not need to match the one generated by reference compiler though we tried to get as close to it as we can.
- Agreeing on the common interfaces and behavior of the compiler was necessary to make synchronization easier.
## Improvements: ## Improvements:
- More checks and error messages like checking if formal parameter type does not match corresponding expression type. - More checks and error messages like checking if formal parameter type does not match corresponding expression type.
- Added more tests to rigorously check program flow. And a test(diff.py) to show a case where our implementation showed better recoverability compared to the reference compiler. - Added more tests to rigorously check program flow. And a test(diff.py) to show a case where our implementation showed better recoverability compared to the reference compiler.
- Added extra error state to the compiler if the actual parameter and formal parameter of the function can not resolve to a type. For example, if function expects an integer type parameter while the caller passes in a string typed param then our compiler will warn the user accordingly

## Grading
Core Tests: 59/59
Extra: 21/21
=========================
Standard tests: 80/80
Work Log: 10/10
Additional Tests: 10/10
Code style: 10/10
Improvements: +1
Overall: 111/110
Congratulations! Your analyzer has solved every test case correctly again. Your improvement is solid and easy to verify. The two-passes design is clear and direct.
## Testing
The additional test cases provided in the `student_contributed` directory are carefully selected and well structured. I am surprised that you managed to reproduce those error messages from reference-implementation. Some of them are weird and probably not worth reproducing, but thanks for reducing the workload on my end.
## Miscellaneous
The Code structure is clear and consistent but could still be improved by removing commented codes (at least in the final version).
The automatic test shell scripts are very helpful. It would be even better if you could organize them with CI tools like travis.ci or gitflow. It is totally optional but it would be fun to construct a CI pipeline.
The worklog contains some typos that could be avoided by adding a spellchecker to the IDE or CI.

# Tests for PA1: ChocoPy Parser
Clone a student repository:
```
TEAM="team"
git clone --branch=pa1final \
https://github.com/nyu-compiler-construction/pa1-chocopy-parser-${TEAM}
```
Build it:
```
cd pa1-chocopy-parser-${TEAM}
mvn clean package
```
Clone the tests _into_ the student repository:
```
git clone https://github.com/nyu-compiler-construction/pa1-tests
```
Run the tests:
