End Of Day Reflection

  • Continuing the Binary Search pattern! Capacity To Ship Packages Within D Days was a great example of โ€œbinary search on answer spaceโ€ โ€” setting low/high bounds and checking feasibility.
  • Find First and Last Position reinforced the left-bound / right-bound binary search template.
  • Deep-dived into BLOB / Object Storage โ€” learned the pre-signed URL pattern (avoid routing files through backend), multipart uploads for large files, and why metadata should always be stored separately in SQL/NoSQL.

Next Day Goal

  • Continue Binary Search pattern
