Description:

Today's Learning Activities:

• Practiced SQL query debugging and correction:

  • Fixed filtering issues (typo in string comparison)
  • Corrected JOIN queries between multiple tables (products & providers)
  • Learned proper use of table aliases and filtering with foreign keys

• Deepened understanding of SQL JOINs:

  • Explained INNER JOIN logic with real examples
  • Understood relationship between id_providers and id columns

• Solved basic JavaScript problem (Sum of two variables):

  • Handled file input using fs.readFileSync and line splitting
  • Ensured exact output format as per specification

• Solved and improved Justifier II problem (Text Right Justification):

  • Handled multiple test cases until N=0
  • Implemented text cleaning (trim + multiple space normalization)
  • Applied dynamic right justification based on maximum line length
  • Added detailed comments for better code readability

Key Learnings:

• Importance of exact string matching in SQL
• Proper JOIN syntax and table relationship handling
• Input processing and text manipulation in JavaScript
• Clean code practices with comments and modular logic

Next Plan: Continue practicing string manipulation and multi-test-case problems.
