@cyqjoseph We did an automated analysis of your code to detect potential areas to improve the code quality. We are sharing the results below, to help you improve the iP code further.
IMPORTANT: Note that the script looked for just a few easy-to-detect problems only, and at-most three example are given i.e., there can be other areas/places to improve.

}Suggestion: Consider applying SLAP (and other abstraction mechanisms) to shorten methods e.g., extract some code blocks into separate methods. You may ignore this suggestion if you think a longer method is justified in a particular case.

possible problems in commit ee190cf:
Done C-DetectDuplicates
This commit introduces a significant enhancement to the project to
filter for duplicates.
Added isDuplicateTask method in TaskList.
- For Deadline tasks, it checks for duplicates based on both name and deadline time.
- For Event tasks, it verifies if either the start or end time, along with the task name, is identical to an existing task.
- For other task types, a simple name-based comparison is performed.
Modified the addTask method to prevent addition of duplicate tasks.
- body not wrapped at 72 characters: e.g.,
- For Deadline tasks, it checks for duplicates based on both name and deadline time.

Done A-Asssertions
In this commit, assertions have been integrated into the project to improve the overall reliability and maintainability of the code. These additions are focused on ensuring that key assumptions in the codebase are explicitly checked during runtime.

possible problems in commit 58622c3:
Implement Assertions in Various Classes
This commit introduces the use of Java assertions across multiple classes in the project to validate assumptions about the program's state. Assertions are added to ensure that the program operates under expected conditions, enhancing the robustness and reliability of the code during development.
Changes made:
1. TaskList Class:
- Added assertions to check if task-related operations are
performed with valid indices and non-null task objects.
2. Storage Class:
- Inserted assertions to validate non-null task lists and the
existence of the file after creation.
3: Parser Class:
- Added assertions in date parsing methods to ensure non-null
and properly formatted date strings.
- Implemented assertions to verify non-empty and non-null user
input strings.
- body not wrapped at 72 characters: e.g.,
