Asterisk Classes: Debugging Strategy

  • The K-Map Grouping: Always look for Octets first, then Quads, then Pairs. The larger the group, the simpler the expression!
  • SQL Syntax: Never forget the semicolon ; at the end of your queries. Suffixes are important for examiners.
  • Algorithms: Write the logic in step-by-step English first, then provide the pseudo-code. It ensures partial marks even if the code has a bug.
