https://pastebin.com/qMTBF9Ff This is the output list from the code provided in this blog. As the prize will be distributed among these ranks but I'm not sure whether is it correct or not. So just for clarification is there anyone who got some info regarding prizes. Please mention it. Thanks

https://pastebin.com/qMTBF9Ff According to this list does anyone get any notification or mail regarding prizes? Please let me know if someone get any information.

It is well known that sqrt() will not feasible to calculate square root of large numbers. So it's better to pass a long double to it or use sqrtl for accurate results. I did the same mistake long ago and learn this fact. The contest are not just for rating or prizes. It is a tool to learn and enhance your thinking ability.. With this question many of us will learnt how to overcome with such an issue.

So don't take it in a wrong way.

Is this contest will be unrated? I agree that this contest is not easier like other Div2 contest but it's has really challenging Questions and brain boosting to solve them. Those who suffer in problem B, I have simpler solution so that there will be no precision error.

You can also use sqrt(x+0.5) for calculating square root of x for even x be in long long int. It will removing error from square root function. I just use this and got Aced. This will even help in large number where sqrt fails due to large calculation and help in such case with this small adjustment gives you right answer.

Please tell me wheather the contest is rated or not ?

A single problem is not the basis of the whole contest. Even the quality of questions from A to H had a very good level and logistics. Defaming it is completely inappropriate way. Even DMOJ is not even a very popular platform that people are aware of that problem.

How can we get to know that the contest has become unrated? Is there any announcement or they just don't update the rating ?

In a general div 1 or div 2 contest the change is rating occur just after because of no hacking round in them. While in div 3 contest there is a 12 hour hacking round and after that there is a 3-4 hour system testing, and within a day the rating got update but why is it taking soo much time in this contest? Can somebody please mention the reasons behind this.

The following is the wrong algorithm, sorry for this.

I guess it is better to use trie data structure that will reduce the time complexity to O(26*N) but it effectively use to give number of distinct substrings as you want to calculate.
