I know this is not the platform to ask this question. I am kind of helpless and this is very difficult to find answer only googling about china from outside of it. This week my family came into shock to know that my elder brother has serum creatinine level 10, which is stage 5 of CKD. Doctor here in Bangladesh give advice to start dialysis immediately and possible kidney transplant in future. We heard that there is good treatment is available in china to reduce the serum creatinine level by traditional chinese treatment but don't able to found enough research resource about that. Codeforces is a great platform for people all around world of kind heart and good amount of chinese community is also present here. Anyone can provide me any necessary links, document, possible review of kidney treatment or any kind of information will be a great help for me and my family. Have a good day.

Hello Codeforces :)

Good Day everyone . Last week I was told to set few problems for my university's intra contest. I was thinking to set a unique idea problem that no one solved before . But what i observed that whenever i came up with an idea , it was something related with other task that i solved earlier . Problem setting is a creative task . It may not possible in a short time limit i know . Once I heard from one problem setter that it may take time of one month to set a genuine problem . I do have some experience to set problems for some online and onsite contest . But in every case i first came up with solution ( a well known pattern or common pattern ) then set story for that pattern problem . May be that is because i amn't very good problem setter and neither good problem solver :p . I think its not only mine but a lots of people question what is your motivation and thinking process behind the problem you set ? How to set unique problem that may not influenced by any other problem task available online ? Thank you all :)

Good Day everyone . Can anyone please tell me the process how to solve this problem . Thanx in advance :)

Good Day everyone . I would like to know what is the solution process for this problem . Thanx in advance :)

Can anyone describe the process and algorithm to find MST on directed graph . i found this Chu-Liu/Edmonds Algorithm but its not clear to understand . Thanx in Advance :)

Its around a year i am in programming contest field, yet i haven't improve so much. Only 2 more years left in my academic study,i know there is no way but practice more and more. It will very grateful to me if anyone suggest the way , strategy you prefer to follow when you have a certain goal like a contest in front of you . If you also suggest what algorithms i must know to do well in competitive programming contest, the way to improve Dp problem solving skill . Thank you all.......:)
