Cosmos: Add some advanced data structures

[abhishekjiitr]

I would like to add some advanced data structures like Binary Indexed Trees, Segment Trees, Tries and more in the _data structures_ folder. Would love to work on this stuff! #hacktoberfest

[AdiChat]

Go for it 👍

[abhishekjiitr]

@AdiChat should I create a separate folder for _advanced data structures_ or should i make changes in _data structures_ folder only?

fenwick tree in cpp and python added please review PR #184 @AdiChat

[AdiChat]

@abhishekjiitr Create sub-folders for each type. Like a folder named fenwick_tree for code of fenwick tree in various languages. 👍

[AkshGautam]

@AdiChat i have already added fenwick tree in two languages. @abhishekjiitr can add segment tree and other DS.

[abhishekjiitr]

[abhishekjiitr]

since a lot of advanced data structures have been accommodated, shall we close this issue @AdiChat ?

[coffe2code]

Can I add code in C++ for AVL trees, Red-Black Trees etc.

[abhishekjiitr]

sure, just make sure these things are not done by someone else already!
