I am glad to invite you to Data Structures' Contest #1, which will take place on Saturday, December 7, 2019 at 15:00 UTC-5
I have learned a lot of things on the last months and have much fun in participating in the competitions. Now, I want to contribute to the community by proposing some problems from data structures. I hope that you will find something interesting in solving them.
There will be roughly 7 problems.
Good luck to the participants!! See you on the scoreboard.
