Hey @RodneyShag, I have saved most of all my Hackerank solutions and I would love to contribute them to this repo for the C++ solutions part. So can you let me know what I should do next?
FYI, the problem has been changed at
https://www.hackerrank.com/challenges/java-priority-queue/problem
so your solution no longer works.
Your solution is wrong โ try a a b b a a a b
I tried google directory generator for HankerRank solution, but no satisfactory results.

Moreover, I think empty content should be allowed.
Hi @RodneyShag,
The solution for Weather Observation Station 8 in SQL is wrong.
It wasn't printing anything on the output when I checked while solving the challenge on Hackerrank.
SELECT DISTINCT CITY FROM STATION WHERE CITY REGEXP '^[aeiou].*[aeiou]$';
This worked for me.

If you implement Java List using arrays, you get long insert/delete. If you implement it using lists, you also get long insert/delete, so it buys you nothing. Arguing that a list is somehow better than an array in this context is simply misleading the learners. (Actually, arrays should be quicker because of HW acceleration and better locality.)
BTW, what you need here is an implicit treap. But that is not a standard collection and you should provide it yourself as a data structure for this task.
Hi,
I like your work on HackerRank problems. But I noticed a potential error in your "Java String Tokens" solution. It passes all test cases provided on HackerRank. But here's one customized test case I came up with: the string is "@@@ I am ok. How about you? ??". Maybe you are interested in looking further into it.
Thank you for your time.
