I would love to contribute my codes for your DSA repository

Hi ! I would like to contribute to your code. I have implemented stacks, queues and Binary Tree and other basic data structures in C++ and would be glad to share them for Hacktoberfest. Along with this I have also implemented other sorting and searching algorithms. Would be glad if you can assign this project to me as well. Hoping for a nice collab :)
