Data Structures and Algorithms

Most people prep for coding interviews by grinding hundreds of LeetCode problems and hoping the right one shows up. Then the interviewer asks a variation, and they freeze. This course takes the opposite approach. Instead of 150 solutions, you'll master the ~20 patterns that actually generate them — sliding window, two pointers, monotonic stack, backtracking, graph traversal, dynamic programming, and the rest. Every lesson teaches one mental model: when to reach for it, the exact template, and how to adapt it. By the end you'll look at any unfamiliar problem, read its clues, and know which pattern fits. Across 44 lessons you'll cover every problem in Blind 75, NeetCode 150, and the Grokking pattern set — in a deliberate, prerequisite-ordered path that builds from complexity basics to a master "decision tree" and live interview execution. Worked examples are language-agnostic, then rendered in your language and aimed at your target companies. You don't need to be a genius or memorize everything. You need a system. Enroll and build one that makes the next variation feel familiar.
