: One of the most effective strategies involves sorting algorithms and problems into three buckets: Easy (can solve instantly), Intermediate (can solve with a hint), and Hard (topics you currently avoid). The goal is to systematically move all items into the Easy bucket.
: Converts slow searches into constant-time lookups for frequency or duplicate checks.
