Focus cues

A few gentle nudges from the current data.

  • You have 6 problems due for review. Great place to start before taking on something new.
  • 1 problem(s) are currently in progress. Finishing those may give you more signal than opening five more tabs.
  • Most common topic: Arrays. If that reflects your actual interview mix, nice. If not, it may be time to rebalance.

Used hash map on second pass. Need to remember to call out time/space early.

Reflection summary

Comfortable. Good warm-up problem before deeper array work.

Mistakes / friction

Started explaining brute force too long before pivoting.

Takeaways

Lead with tradeoffs, then implement the optimal hash map solution.
