Complexity Analysis

O(N²) Quadratic Time

Execution time grows as the square of input size. Often seen in algorithms with nested loops over the same dataset.

Steep Growth

Small increases in input lead to significant time jumps.

Nested Loops

Typically 'for i in N' containing 'for j in N'.

Limit

Unsuitable for extremely large datasets (N > 10,000).

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.
