The worst-case time complexity of building a binary heap by successive insertion of n elements is:

  • AO(n log n)
  • BO(n²)
  • CO(n)
  • DO(log n)
The system

Four moving parts. One rank going up.

Everything here maps back to the actual GATE CS paper — no filler, no fluff, no “motivational” noise.
