Finally after 10 tiring days the A̶u̶g̶u̶s̶t̶ November long concludes. Lets share our approaches for the problems here while editorials for problems come out (at this moment none n̶o̶t̶ ̶a̶l̶l̶ of them are out)? Got any interesting approach which you cant wait to share? The wait is over
So, which was your favourite problem? I had best time solving ̶I̶n̶t̶e̶r̶a̶c̶t̶i̶v̶e̶ ̶M̶a̶t̶r̶i̶x̶ ̶:̶)̶.̶ MAGICHF2 ̶T̶h̶e̶ ̶p̶r̶i̶n̶c̶e̶s̶s̶ ̶g̶a̶v̶e̶ ̶m̶e̶ ̶a̶ ̶r̶u̶n̶ ̶f̶o̶r̶ ̶m̶y̶ ̶s̶c̶o̶r̶e̶ ̶x̶D̶ ̶-̶ ̶s̶o̶ ̶I̶ ̶l̶e̶t̶ ̶h̶e̶r̶ ̶s̶t̶a̶y̶ ̶w̶i̶t̶h̶ ̶d̶r̶a̶g̶o̶n̶s̶ ̶a̶n̶d̶ ̶b̶e̶ ̶b̶y̶ ̶h̶e̶r̶s̶e̶l̶f̶ ̶t̶h̶e̶n̶
But on a serious note, anyone who was able to MAXDTREE s̶a̶v̶e̶ ̶t̶h̶e̶ ̶p̶r̶i̶n̶c̶e̶s̶s̶ ̶(̶o̶r̶ ̶p̶r̶i̶n̶c̶e̶.̶.̶.̶? :p). I kept on getting TLE W̶A̶ for larger TCs, so I appreciate any approaches for it
P.S. - If someone can write something on interpolation (s)he is most welcomed. I invite @gorre_morre and @algmyr for this task. ( Tagging here don’t send any notification.) I derived some required equations for CHEFEQUA, didn’t check the correctness of those equations because I knew even I these are correct then time left for the contest in insufficient to implement those.
Let the discussion begin!
