Big-O, Arrays, and Strings

Build a reliable cost model, then learn the state, pointer, accumulation, and boundary patterns that make array and string solutions predictable.

  1. 01 Big-O and JavaScript's Hidden CostsLearn to describe growth, price every operation inside a loop, and defend a complexity analysis. 55 min
  2. 02 Arrays and Immutable StringsUnderstand the JavaScript operations beneath array and string interview solutions. 50 min
  3. 03 Remembering What You Have SeenReplace repeated searches with three reusable questions: have I seen it, how often, and which partner is needed? 65 min
  4. 04 In-Place Array PatternsUse read/write boundaries and safe traversal direction to transform arrays without losing unread values. 70 min
  5. 05 Prefix, Suffix, and One-Pass StateSummarize the past so each position can be answered without rescanning the array. 65 min
  6. 06 Matrix Boundaries and TransformationsTurn grid traversal into explicit shrinking boundaries and verify in-place transformations geometrically. 65 min
