📖 LESSON

Optimization Techniques

Advanced optimization techniques help push the limits of what's possible within the given time constraints.

Precomputation

Computing results once and using them multiple times. (e.g., Prefix Sum, Sieve)

Pruning

Cutting off branches of a recursive search that cannot lead to a solution.

Meet-in-the-middle

Splitting the search space into two halves and combining results.

Lazy Evaluation

Deferring calculation until the value is actually needed.

💡 Rule of Thumb

Always optimize the **bottleneck**. Reducing an O(N) part to O(log N) doesn't help if there's another part of the code that is O(N²).
