Since January 2021 I resolved many of the exercises from the category Problem-Solving. To do so, I used Java language. On the pages there are countless number of algorithms, challenges and tasks. Usually I try to resolve one or two per day.
Of course HackerRank does support rankings, and every user has his own rank. The same for me, but because my score grows rapidly and I go up in the ranking ledder, I will publish my score if I reach the first 50k users level in the area of Problem Solving.
