Grokking the Coding Interview Patterns: Includes Topic Tutorials Plus LeetCode Questions & Solutions in JAVA ☕️
This repository contains topic tutorials on "must know" coding interview patterns, their associated LeetCode questions and solutions in Java programming language. It is based on "Grokking the Coding Interview: Patterns for Coding Questions" by Design Gurus.
Each section is structured as follows:
* Bitwise XOR L Bitwise_XOR_Tutorial.txt (What is Bitwise XOR (exclusive OR)?) L Problem_1_Single_Number.java (LeetCode Question: 136. Single Number) L Problem_2_Two_Single_Numbers.java (LeetCode Question: 260. Single Number III) L Problem_3_Complement_Of_Base_10_Number.java (LeetCode Question: 1009. Complement of Base 10 Integer) L Problem_4_Flip_And_Invert_An_Image.java (LeetCode Question: 832. Flipping an Image) Before solving Leetcode problems, make sure you are familiar with the following:
* Fundermentals of programming in Java Language * Collections in Java L Interfaces: Set, List, Queue, Deque L Classes: ArrayList, Vector, LinkedList, PriorityQueue, HashSet, LinkedHashSet, TreeSet, etc. * Data Structures and Algorithms in Java L Data Structure: Stack, Queue, Graph, Tree, etc. L Algorithms: Sorting, Searching, etc Coding Interview Patterns are classified according to skills level:
6. LinkedList - In-Place Reversal
8. Island Pattern (Matrix Traversal)
2. Tree - Breadth First Search
8. Union Find (Disjoint-Set Data Structure)
Below is a visual representation of the three main pillars that make up Data Structures and Algorithms for Coding Interview's i.e. Data Structures, Algorithms, and Problem-Solving Techniques. It demonstrates the relationship between these three pillar's of Computer Science knowledge.

Neetcode Roadmap: This is a structured approach to preparing for technical interviews, particularly for software engineering roles. It was created by NeetCode, a popular YouTube channel and website that offers a variety of resources for coding interview preparation. The roadmap is designed to help candidates tackle common interview topics in a systematic and comprehensive way.
