The April Challenge 2011 is over!
The contest went through a few hick-ups this month, we faced downtime of our judge SPOJ for about 10 hours, due to some construction work which caused a network breakdown in Poland, thats where our judge is located. We therefore extended the contest by 24hours to make sure no one lost out during this downtime. We also had a few changes in our test cases during the contest and had to re-judge the problems L2GRAPH and RECTCNT.
Before we move on to the next section of the blog post, a special mention of the people who made this contest possible:
Zac Friggstad, AnhDQ and Snigdha Chandan were the problem setters while Rajiv Kumar was the diligent tester of this month’s contest.
Lets look at some Statistics and then move on to see the final winners list.

Welcome to the April Programmer of the Month edition!
This month we have with us Md. Mabubul Hasan(aka Kungfu Panda) who is our Programmer of the Month. Mahbubul has been part of CodeChef since July 2009 and has taken part in almost all CodeChef’s contests, just at the age of 24 he is already a great programmer. He is ranked 5th in the long format and 15th in the shorter format of the contest. We hope this is just the start and we have lots to see from this great mind. On behalf of the CodeChef team, we wish him good luck for the future. Now let’s see what Mahbubul has to tell us about himself.
Name: Md. Mahbubul Hasan
Institute: Bangladesh University of Engineering and Technology
User id: white_king
Twitter ID: firstname.lastname@example.org
Brief introduction about yourself:
I graduated from Department of Computer Science and Engineering from Bangladesh University of Engineering and Technology (BUET) in 2011. Currently I am lecturer in this institute. I have a younger sister. My father is a Professor and my mother is house wife. I am a bit shy and introvert person infront of strangers. But I am quite talkative with my close friends. I have a very bad memory, I forget very easily. My face recognition system is very bad. Very often I forget my close friends name, cant recognise familiar one and also make mistake some stranger as my friend
How/When did you start programming?
In grade 6, I saw a grade 11 text book describing QBasic at back. I was very happy when my first programme ran succesfully. After that in grade 7, I came across visual basic and made some GUI based programme. I was really very excited at that time to make a GUI based programme so easily. Later, I helped my father making a result processing database software in visual foxpro. In grade 9, I saw a code of racing game in C in a computer magazine. I coded all but it did not compiled properly. And I did not know C then. So I learned C from a book which seemed quite complex comparing to Basic languages. After learning basic of C, I learned about online judge uva and tried to solve but without success. I tried for a month but out of luck. Could not solve a single problem. Then I found a book where there were about 50 solves of acm problems. I learnt that conio.h is not allowed in uva then And from then I started to solve uva problem and never turned back. I solved lots of problems learned lots of algorithms, participated in many online contests, solved in different OJs. Participated in Bangladesh Informatics Olympiad and became champion, but for visa problem we could not attend IOI in Poland in 2005. Later we were invited to participate in ICPC Dhaka site 2005 unofficially. We became runner up there beating all the universities of Bangladesh, just Chinese team from Fudan University was ahead of us. In 2007 we became champion of dhaka site, 2008 runner-up. I participated in World Finals 2008 and 2009. I also participated in Google codejam India site. From 2006 to 2011 we participated in over 30 national contests and became champion in 27 contests.
What do you do when you’re not programming?
I love math. I sometimes read articles, books on mathematics. I also wrote two math books for our school kids. Professor M Kaykobad helped me a lot in this regard. I like to watch movie. I also like songs specially old songs which might be a bit uncommon among others.
What do you like most about CodeChef?
Codechef is a very good platform for programmers. I specially like their devotion to bring up the indian teams. Being a problem setter in ICPC Kanpur site, I knew genorosity of DirectI. I like the long contest and short contest both. But recently I am not getting time to participate fully, thats what makes me sad. There are lots of things to learn from Codechef monthly contests. I sometime envy my juniors that they are getting the opportunity to participate in these great contests but in our time there was not such.
How many hours a day do you program?
It depends. I still like to participate in Codechef, Codeforce. In my study years, I used to spend around 6 to 8 hours but now it is just bound to few online contests only.
If you could eat dinner with any famous person (past or present), who would it be and what dish would you have?
I would love to have some dinner with the coding giant Petr and Tiancheng Lou aka ACRush. Any kind of dish will be fine for me if they give some delicious desert after dinner
What is the secret to being a good programmer?
There is no secret. Work Hard, try to participate in all the online contests and try to know the solutions of the problems that you could not solve in the contest.
What are your plans for the future?
I don’t know exactly. But I just want to take right decision at the right moment. I like research. So I think I would go for a Ph. D. and then some research group. I also have interest for industry. So I also might join some good company and see if I like there, in that case I am gonna stay there for long.
I would like to thank my family, my friends, some online programmer friends who helped me a lot. I also like to give special thank to Shahriar Rouf for being my team mate from the first contest till the last one in national contests, he has been a great support.
