: 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.

: Sorting (Merge, Quick), Searching (Binary Search), and Recursion.

: Arrays, Linked Lists, Stacks, and Queues.

: Big O Notation and space-time complexity analysis.

: Trees (Binary Search Trees, Heaps) and Graphs.

: Converts slow searches into constant-time lookups for frequency or duplicate checks.

For those looking for structured practice, repositories like RashadTanjim’s DSA Collection offer implemented examples in C++ for these various topics.
