Throughout the last year (2020) I resolved all exercises in the CodingBat challenge. You may read about this also in my Portfolio page.

The challenge consisted of 317 algorithms of different scale of difficulty, so it took me a while to complete it all. According to the CodingBat’s reports, the hardest for me were:

  • AP-1 “Common Two”
  • Array-3 “fix45”
  • Array-3 “Can Balance”

A sample output from the CodingBat test data you can see below:
