✨Roadmap to learn DSA in 2022

👇check out 1️⃣Learn a programming language

->choose from C++, Java or python only.

->There are huge communities and lots of resources in C++ and Java so going with one of them will help you!

✨𝗕𝗜𝗧𝗖𝗢𝗜𝗡 𝘃𝘀 𝗘𝗧𝗛𝗘𝗥𝗘𝗨𝗠 --The difference should be clear!!

-->Bitcoin is the first and the biggest (according to market cap) cryptocurrency. Bitcoin was introduced in 2009.

-->Ethereum is a far recent blockchain that was introduced in 2015.

✨Coding interviews are majorly focused on data structures and algorithms but many times CS fundamental subjects also have been asked in interviews

Which are these topics ??????

👇Check out!!! 1️⃣Object-Oriented Programming

-->Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic

✨Learn algorithm

⚡INSERTION SORT

👇read out -->Insertion sort divides the given list into 2 parts.

-->The sorted part of the list at the beginning of the list and the unsorted part of the list at the end of the list.

-->It starts with the assumption that a list with a single element is always sorted.

✨5 Algorithms you should learn if you are preparing for data structures and algorithm-based coding interviews

👇A Thread 1️⃣ kadane's algorithm

Problem statement-
Write an efficient algorithm to find the sum of contiguous subarray within a one-dimensional array of numbers that has the largest sum.

✨Coding interview patterns and their questions {part-4}

A thread 👇 ✨Pattern 1: Bitwise XOR
XOR is a logical bitwise operator that returns 0 (false) if both bits are the same and returns 1 (true) otherwise. In other words, it only returns 1 if exactly one bit is set to 1 out of the two bits in comparison.

✨5 Books for Data structures and Algorithms

👇A Thread 1) Introduction to Algorithms
-> Known as the Bible of algorithms.

✨Algorithms that you MUST know

👇 ✨SEARCHING
1️⃣Linear search
2️⃣Jump search
3️⃣Binary search
4️⃣Depth first search
5️⃣Breadth first search

A Thread 👇 ✨Pattern 1: Merge Intervals
This pattern describes an efficient technique to deal with overlapping intervals. In a lot of problems involving intervals, we either need to find overlapping intervals or merge intervals if they overlap.

Solving a problem of the coding interview is mainly about recognizing patterns. Here are some patterns you must know:

👇Thread If an input array is sorted then
- Binary search
- Two pointers

✨Learn DSA - Bit-manipulation roadmap 👇 Bit-manipulation is the underrated topic, it is confusing too. I have curated the best resources to learn bit-manipulation for coding interviews.

Bitcoin is not just a currency. It is 3 layered technology stack.

read👇 The Word Bitcoin is used to simultaneously denote three different things, it might be confusing for beginners. Let me Break it out so that you can understand it at ease.

Bit-manipulation is confusing. not anymore!

Learn bitwise operator just by reading this-

A thread👇 ✨Introduction
-> Bitwise Operations let you manipulate numbers at bit level. Bitwise operations are faster than regular operations.

There are main 6 bitwise operators:
1)Bitwise AND
2)Bitwise OR
3)Bitwise XOR
4)Bitwise left-shift
5)Bitwise right-shift
6)Bitwise complement

Real-life applications of Various Data Structures.

A thread👇 ✨ STACK
1) UNDO option

2) Text editor, you push letter by letter to the stack so you erase back.

3) Recursion (in built stack)

If you want to crack coding interviews, you must learn data structures and algorithms. But you might be confused about where to start as there are lots of resources.

No more confusion. Here is the complete path to learning DSA.

A thread 👇 When I entered college I got different advice from different people, It was pretty hard for me to start. But now in a span of one year, I have solved over 400 questions of DSA on various judges.

I have put all my experience and suggestions in the below thread.
