Hey @l_returns ,

I went through your editorials, and edited the first half to what would seem ideal to me. You can refer to that, and then at the latter part of the editorial to check the differences, and note formatting syntax etc. :slight_smile:

Some things I would like to point out-

  1. I love your spirit of explanation. But it is an art to know when to explain very elaborately and when to refrain from that. What we call, Abstraction. :). I loved how you went on to tell the trick in detail, but at the same time, as you can see from editing history, I removed a bit of redundant explanations from the editorial. Too much of redundant explanation, where things are trivial bores the reader, and makes him feel as if editorialist is assuming him to be a kid/total-noob. Not to mention it unnecessarily makes the editorial lengthy!
  2. Formatting and presentation can be improved. Check out the format of latex etc. from the part I edited. :slight_smile:
  3. A few typos, but thats fine. Make sure there are no typos in headings.

Elaborating n point 1, even I did that when I wrote my very first unofficial editorial. I was a 2 star then, and was able to solve the question after looking at people’s code XD. Check it out here- FEB-17, MAKETRI Editorial (Unofficial) - editorial - CodeChef Discuss

See its such an extreme case of elaborate explanation! XD Criticthat editorial, see how it can be improved, and in the process see if you did that mistake as well! Thats all, I appreciate your sincere efforts :slight_smile:

hello @prnjl_rai

your code is giving wrong answer when ‘n’ is odd and k=3.
Add some more cases to it.

So well explained… loved it! :slight_smile:

This explanation is really helpful. This editorial is clearer than the Official one!

welcome :slight_smile:

for "5 8 " you forgot to print two one’s …

22

okay sure… give me some minutes…

23

Your logic is correct… got AC after some typecasting…

24

just type cast the output of pow(x,y) function to (ll) and that’s it…
