Fast-paced video tutorial covering the core data structures (arrays, strings, sets, hashmaps, trees, graphs, priority queues/heaps) and the recurring algorithm patterns used in LeetCode-style interview questions: two pointers, sliding window, binary search, BFS, DFS, and backtracking, with Big O notation and worked practice problems for each pattern. Aimed at programmers with basic coding experience preparing for technical coding interviews.
