What was
covered.
01
Big O Notation
Time and space complexity analysis for writing efficient, scalable code.
02
Arrays & Strings
Core data manipulation, sliding window, two-pointer patterns and beyond.
03
Hash Tables
O(1) lookups, collision handling, and real-world frequency/count problems.
04
Linked Lists
Singly, doubly, and circular lists — reversal, cycle detection, merging.
05
Trees & Graphs
BSTs, AVL trees, BFS/DFS traversal, shortest paths and topological sort.
06
Stacks & Queues
LIFO/FIFO patterns, monotonic stacks, and priority queues with heaps.
07
Recursion & DP
Memoization, tabulation, and classic problems like knapsack and LCS.
08
Sorting & Search
QuickSort, MergeSort, binary search — and knowing when to use each.
01
FOUNDATIONS
Built rigorous understanding of how data structures work under the hood — not just how to use them, but why they exist.
→
02
PATTERN RECOGNITION
Learned to identify which algorithmic patterns map to which problem types — building a mental toolkit for any interview question.
→
03
APPLIED TO CODE
Every concept shipped into real code — writing optimized solutions that I now apply daily in production engineering work.
Always
learning.
