What you will learn
- Most interview problems are variations of a small set of patterns.
- State the brute force and its complexity before optimising.
- Sliding window turns many O(n²) substring problems into O(n).
Patterns beat memorisation
Solving hundreds of random problems is slow and forgettable. Interview problems cluster around a few patterns, and recognising the pattern is most of the work.
Always start by stating a brute-force solution and its time and space complexity; then look for the pattern that removes the repeated work.
