Off-by-one errors (OBOEs) are among the most common logic bugs, even for seasoned developers. These bugs occur when a loop or operation goes one iteration too far or one iteration too short-leading to incorrect results, missed elements, or crashes.

They usually occur in:

  • Loops
  • Array indexing
  • Ranges
  • Substring operations
