Sweepline Technique

The sweep line technique processes geometric or time-based events in sorted order and maintains an active set that reflects the current state at the sweep position.

Offline Query Processing

Offline query processing means you collect all queries first and answer them later in a smart order that makes updates/queries cheap.

Mo's Algorithm

Mo's algorithm answers many range queries offline by reordering them to minimize pointer movement along the array.

Line Sweep

Line sweep (plane sweep) is a technique that processes geometric objects by moving an imaginary line and handling events in sorted order.

LIS Variants

LIS variants extend the classic longest increasing subsequence to handle non-decreasing sequences, counting how many LIS exist, and maximizing the sum of a subsequence.
