1. Integrated Development Environment (IDE) debugging capabilities, including syntax error detection, variable inspection, and runtime error tracing. 2. Logical and syntax error identification in pseudocode statements, covering operations like STR_TO_NUM, MID function, and condition evaluation with date values. 3. Expression evaluation involving Boolean logic, modular arithmetic, and conditional simplification for program decision-making. 4. Algorithm design for generating strings with specified characters and lengths, flowchart representation, and pseudocode for date assignments. 5. Points-based reward system structure, including data structure selection for customer information, and stepwise refinement for band-based point calculation algorithms. 6. Program development models comparison (e.g., waterfall vs. agile), testing methods for interactive web applications, and structure charts with parameterized modules.
