Coding Interview – Essential Topics & Concepts πŸš€

1️⃣ Data Structures

Arrays & Strings – Sliding window, Two pointers.

Linked Lists – Reversal, Merging, Cycle detection.

Stacks & Queues – Monotonic stack, Priority queue.

HashMaps & HashSets – Frequency counters, Two Sum problem.

Trees & Graphs – DFS, BFS, Binary Search Tree (BST), Dijkstra’s Algorithm.


2️⃣ Algorithms

Sorting – QuickSort, MergeSort, HeapSort.

Searching – Binary Search, Ternary Search.

Recursion & Backtracking – N-Queens, Subset sum.

Dynamic Programming (DP) – Fibonacci, Knapsack, Longest Common Subsequence (LCS).

Greedy Algorithms – Huffman coding, Activity selection.


3️⃣ System Design Basics

Scalability & Load Balancing – Horizontal vs. Vertical Scaling.

Database Sharding & Indexing – Efficient data retrieval.

Microservices & Monolith – Pros & Cons.

Caching Strategies – Redis, Memcached.

Message Queues – Kafka, RabbitMQ.


4️⃣ Coding Interview Strategies

Understand the Problem – Read carefully, ask clarifying questions.

Plan Your Approach – Write test cases, consider edge cases.
