Pattern Recognition Drill
Practice identifying the pattern before coding anything at all.
- •Can I list the strongest clues in the prompt before coding?
- •Do those clues point to one pattern more strongly than the others?
- •Can I justify the pattern choice in one sentence?
Pattern Recognition day is pure classification practice. You are not trying to code fast. You are trying to see the shape of the problem instantly. Once that reflex gets strong, solving becomes much easier because you stop wasting energy on bad first guesses.
Seeing the pattern early is often half the solution.
- 1Read the prompt and ignore implementation details for a moment.
- 2List the strongest clues: sorted, range sum, duplicates, levels, dependencies, and so on.
- 3Name the pattern that best matches those clues.
- 4Only after that decide how you would implement it.
If you start coding before you classify the problem, you usually end up testing the wrong strategy for too long.
Product of Array Except Self
Two passes, no division: left-to-right builds prefix products, right-to-left builds suffix products. Multiply them together at each index.
Maximum Profit in Job Scheduling
Sort jobs by end time. DP: for each job, binary search for the last non-overlapping job and take max(skip, job profit + dp[prev]).
