Data Structures and Algoritm Notion Notes

I am learning Data Science and Algorithms, so I decided to create Notion notes for it. 
My notes are having important topics like:
Arrays, Linked Lists, Stacks, Queues, Binary Trees, Binary Search Tree, Maps, STL and my Competitive Programming Template along with Link to important Questions.

The notes use C++ for all the problems.

BEFORE YOU BUY

* You can get the content for free online if you browse Geek4Geeks, or other resources. It's just that, having them on Notion comes very handy for quick revision.
* Remember these are Notes made to REVISE a topic and NOT learn it, if you want to learn DSA, I would highly recommend buying a Udemy/Coursera course.
* I update these notes as I learn new topics. Currently, notes are not having Maps and Queues.
