While in early times I use to struggle with bits generally it appears in question B then I gave time read it patterns and I am able to answer it now it mostly appears at c and I cannot solve that after contest when I try toh find answers it always associate a new property of xor .,.....how to overcome it .......i already done 2-3 yt playlist and knows the basic

Got -ve delta after scoring nearly 4200 in common rank list and 5200 in final list while being already at grey level...........am I the only one who is experiencing that gaining delta became very difficult as compare to last year ........ earlier years scoring these rank at pupil gains me delta......... earlier I was >1300 rated ....now even not a pupil...........

company donnot ask for it, but its most effective way in india to get a referral.......for people belonging from lower colleges it very hard to get shorlisted for OA without referral

Thank you aakarsh-2004 for mentioning the issue

I was about to touch speciality when I left 1.5 years ago........now I went back to grey......I earlier thought my skills are degraded ......it feels so bad .....as from lower tier colleg I came back here to gain expert postion to get a top tier companies's referral.......

think of those who come from lower colleges and trying to increase their rating because its the only way to prove themself ......but now due to cheating they cannot score and also there is not certainity if they achieve good rating by themself will company shortlist them thinking that genuine people are also cheater.............(for those who will come and make advices if you want job do leetcode,dev,open source........keep your mouth shut...coz you donnot some college have 0 oppurtunity to prove as a student except higher rating like cm ,expert,master)......

can anyone please tell me why this fail on test case 4 i will be gratefull if someone can find the error for me SUBMISSION

Not only few people are employable but only few have cleared big tech giant from a 3rd tier college and mostly those are CM, Master.....

For a 3rd tier college student in India CP is the only(or 1 one of very less) way to get in big product base giant..... No matter whether you have to build crud app only in jobs.....if you have only experience in building a crud app with a 3rd tier college tag even your resume donnot get shortlisted offcampus..... Only a 3rd tier college student with dream of getting into tech giant know what these tag of master and CM mean to them and how this is their only way to shadow there 3rd tier college in resume to get their resume shortlisted in tech giant like google, Microsoft, atlassian etc

we want to become a CM and Master to have a feeling that i have achieved something big (without cheating) and want to show in industry that we are capable of high logical thinking for jobs (without cheating) but because of cheating we are unable to achieve this as rating based on rank.....so how Whether people cheat or not is not our concern.

Hope to tackle C

Thanks I got it

Can't figure out C then guess it in same way like many others have done.... Still get wrong ans on test case 2 ... Can anyone tell me why this fail.... Same logic many other have passed it

My soln

I have done the same thing why this not work? code__

I changed the code for being sum =0 then also it give wrong ans at case 5k in test case 2 .....can you say why....300746771

Can you tell me that plz?

I changed the code for being sum =0 then also it give wrong ans at case 5k in test case 2 .....can you say why....300746771

Actually I earlier I tried to make sum of 2 row or 2 column or 1 row and 1 column equal i.e 1st and last then I change it for sum =0 still wrong why

I changed the code for being sum =0 then also it give wrong ans at case 5k in test case 2 .....can you say why....300746771

But it says sum of values in each rows = x and sum of values in each column = x then why we need this sum of all column = sum of all rows(I.e sum_row * n = sum_column * m)

Is it just me who think B>>>>>>>>>>>>>>> C+D

thanks

submission 1 submission 2 CAN ANYONE PLEASE EXPLAIN WHY BOTH OF MY THIS SOLN GIVE WRONG ANS ON TEST 2 TODAYS DIV 4 B

Hope to reach....... Realising NO HOPE LEFT

Bits

IS B1 is of Dynamic programming and if yes how 9k people manage to solve dp question ......leaving garden of green back to concrete layer of grey

are you thinking to pre calculate a-b or a-b/2 or a-b/3 respectively for single digit ,double digit and triple digit......?????

how is it 1e4*1e4*100 in brute force....??? beacuse after these 3 loops for(n>9) we have to convert it into string then add it to string for a times and pop back it for b times ....to get the final string that we convert into integer of long long??

Some tips how you went from range of more than 8k ranks to 1k rank in last round in just 2-3 months?? Did you followed some course or what??

I already gone into 3rd year.....but still on newbie
