  1. 06.01
    Asymptotic Notation: Upper Bounds, Lower Bounds & Tight Bounds

    Deconstruct asymptotic notation. Contrast Big-O, Big-Omega, and Big-Theta, understand dominant terms, and eliminate hardware-specific constants.

    4 min
  2. 06.02
    Auxiliary Space Complexity & Recursion Call Stack Footprint

    Analyze memory scaling. Differentiate between total space and auxiliary space, calculate recursion call stack depth, and optimize for in-place algorithms.

    4 min
  3. 06.03
    Amortized Complexity: The Accounting Method & Dynamic Array Resizing

    Master amortized analysis. Understand why ArrayList.add() is O(1) amortized despite occasional O(N) resizing, and model costs using the Aggregate and Banker's methods.

    4 min
  4. 06.04
    Recurrence Relations, Recursion Trees, and the Master Theorem

    Formulate mathematical recurrence relations for divide-and-conquer algorithms and solve them rigorously using recursion trees and the Master Theorem.
