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. 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)

This coding interview resource is based on "Grokking the Coding Interview: Patterns for Coding Questions" by Design Gurus.

I am an advocate of learning-in-public, so I thought I'd create a public repository to keep all my learning on preparation for FAANGM coding interviews.

Hope you find it useful 😎
