DS section

[rain84]

Hi, folks!

What do you think about idea to add the section with implementation of data structures on different languages?
And also add some samples with a typical usage of this DS.
I think, it will be helpful for the effective solving of the algorithmic problems.

Hello, many programming languages come with various built-in data structures. I believe that some basic data structures do not need to be added to the project. However, for some advanced data structures, or common algorithm templates, such as union-find, monotonic stack, etc., they can be added to the project to help improve problem-solving efficiency.

Currently, the project lacks this series of content, and if you are interested, you are welcome to join in maintaining and iterating improvements.
