In today's Codeforces Round (#763) problem B, I tried finding a pair object in a HashSet. Even after overriding equals() and hashcode() methods, I still ended up with WA on test 4. Here is the link to my solutions: 1) WA Submission using HashSet 2) Working Solution using 2D ...
i am new here and i want to ask how i can submit problems thnx

We know about the O(N2) solution in C, but we did not find a good suitable proof for it (and, using the method, we could achieve faster solutions). You can solve D without the constraint that the segments are contained, but that is harder. It is solvable in (ONlogN). Thank you ...
Note you should print the correct partition of the row of the pearls, so each pearl should be in exactly one segment and all segments should contain two pearls of the same type. If there are several optimal solutions print any of them. You can print the segments in any order. ...
The task is count how many solutions to put N queens in NxN board. I have tried to thought every possible case to improve the performace, but it take almost 50s to run with N = 15. Here's what I've do... Add condition to where clause eloquent relation ...
