Complexity Analysis

Big Theta Notation

Provides a tight bound on the growth rate, meaning the algorithm's complexity is sandwiched between a lower and upper bound of the same order.

Tight Bound

Means the Big O and Big Omega orders are the same.

Exact Growth

Gives the most accurate representation of an algorithm's performance.

Sandwich Effect

Algorithm growth is bounded both above and below by f(N).

Scale

Observe how $O(N^2)$ dominates other functions as $N$ increases.

The Core Principle

Algorithmic analysis allows us to predict performance without hardware bias. By focusing on Big-O, we ensure our solutions remain scalable as data grows exponentially.
