CS Foundations & Interview PrepIntermediate8 modules~4.0 hours hands-on
Advanced Coding Interview Patterns
Master the high-leverage interview patterns beyond core arrays and graphs: binary search, intervals, heaps, monotonic stacks, backtracking, tries, greedy reasoning, and bit manipulation.
// What you'll be able to do- Search values, boundaries, and feasible solution spaces
- Sort events, merge ranges, and reason about overlap
- Keep the next best candidate available efficiently
- Resolve nearest-greater and boundary questions in one pass
