HonestCode: A Blog About Competitive Programming

A weekly blog for me to occasionally talk about competitive programming topics as a meaningful entirely human effort in this world where AI is becoming increasingly integrated into computer science as a whole for both good and bad reasons. Some of the general topics include:

  • Actual algorithm and data structure explanations
  • Contest recaps
  • Practice methods
  • A divulge of my thoughts on AI in the context of competitive programming that is only slightly less Um_nik-like
  • Interesting problems
