Beginner Topic 15 of 51 Algorithms

Brute Force

Trying every candidate solution exhaustively.

How it works

Brute force enumerates every candidate and checks each against the problem constraints. It is simple and correct but often exponential.

Where it is used

Small inputs, verifying faster solutions, baseline for testing.

Common pitfall

Fails to scale: checking all subsets of 40 items is already a trillion cases.

Where it fits in the course

Brute Force is topic 15 of 51 in Algorithms, rated Beginner. It follows Radix Sort. The next topic is Two Pointers.
