Technical Interviews

A repeatable six-step problem-solving process: Read, Observe, Pseudocode, Implement, Test, Analyze.

Recognize 10 essential patterns—Hash Map, Two Pointers, Sliding Window, Binary Search, Stack, Queue, Linked List, DFS, BFS, Heap—and when to use them.

Seven problems worked through with ROPITA, from Two Sum to Number of Islands. Each includes implementation, test cases, and complexity analysis.
