So much Combinatorics in June Long Challenge 2019 (DIV-2)

Don’t get me wrong, I love number theory and discrete mathematical structures but this is just going too far. I feel like core algorithmic / data-structure content is missing. Where questions like Chef Ingredients asked solver to be really creative, it was so combinatorics central. Do let me know if you all feel the same.


This is my first codechef long challenge and felt the same.

I think this long focuses on mathematics :sweat_smile::sweat_smile::sweat_smile:

I agree. I was able to solve the first 5 questions within two days. I could barely solve two questions in the previous long challenges. I think CodeChef wanted to test us on our observation skills and core mathematics knowledge for a change.

True…we would learn a lot more if they include different topics.
