Code Knights Round 14 Result and Problem Analysis ?>

Code Knights Round 14 Result and Problem Analysis

Assalamualaikum everyone. Its been awhile since I did a written analysis instead of a video or straight up, not doing it at all. Although recording a video is much more convenient that writing a blog, nothing beats creating a well authored blog post. That, and also the fact I did not finish this round, resulted in this post, albeit, late, because it takes time to type down these things.

Anyway, Round 14 is the second round after the last round which IIUM’s DSA student is scored for participation. Additionally, its kinda exam period for IIUM student… so… we are seeing a much lower participation, even after including participant from Hebron University, Palestine. In fact, looking at the ranking list, 6 out of 10 participant actually came from Hebron! If they did not participate, we would be looking at only 4 participant!

Code Knights Round 6 Results and Problem Analysis

Assalamualaikum everyone,

Last Saturday, the 6th round of Code Knights was held, with a total of….. 17 participants. Same as last round, which is also the same as the round before. This round is significantly harder than the last round, which was the easiest round by far.

Selection_094
It looks like only 12 participant, but actually there are 5 more down below which tried, but did not manage to solve any problems…

How hard? Well.. if you compare it to Round 3, its.. OK-lah. The winner for this round goes to anas_95 from IIUM, who also won last round. anas_95 was the only participant who manage to solve 4 problems, but he did not solve problem D. It’s nice to see someone from IIUM winning again, but its starting to get boring. Can someone else win next time? stdLn maybe? Heck, I’m even waiting for lim2481284 to make a comeback.

Code Knights Round 5 Results and Problem Analysis

Assalamualaikum everyone,

Last saturday, Code Knights Round 5 was held with a total of 17 participant… which is pretty much the same with round 4. The winner (finally…) goes to anas_95 from IIUM by the virtue of answering all problems faster with less penalty (which is 0). This round is (unfortunately) the easiest round ever with 6 participant answering all problems.

Selection_087

The second place goes to UncleWong from UM and the third place goes to joscmw95 from UTAR. foreveralone, winner of round 4 is at the fourth place. Notable mention includes two time winner lim2481284 from UNITEN which continues his effort of not even trying. You can find the dataset and pdf through the link below:

Code Knights Round 4 Results and Problem Analysis ?>

Code Knights Round 4 Results and Problem Analysis

Update: Announcement for round 5 is out.

Assalamualaikum everyone,

Last Saturday 8 PM (as usual), Code Knights Round 4 was held at… online. This time, we have 17 contestant including several new participant from UM, UTAR, UKM and others. lim2481284, the winner of the last 2 round seems to have lost his edge, finishing at the 14th place. He is probably busy and have other stuff to do.   Meanwhile, shahril, the consistent second-finisher did not participate this time, breaking his consistent-second-place record from the first round and leaving HarshRalph to represent UiTM. The winner for this round goes to a newcomer, foreveralone from UM. He is a newcomer in a sense that he just registered in Code Knights, but not in the sense that he is new in competitive programming. Interestingly joscmw95 actually solved all problem first, but he submitted more wrong submission than foreveralone, resulting in an extra 13 minute penalty compared to foreveralone (each score point is approximately 1 minutes).

Who in the world is capayam? Tell him if we don’t get his phone number, we will ban him.

As you can see in the scoreboard, all problem was solved. Unfortunately, no single question was solved by everyone. Three participant managed to solve all 5 problems. All of these three participant are new participant. The difficulty of the problems this time seems to be more towards the easy side, but then again, if foreveralone, joscmw95 and UncleWong did not participate, (remember, they were new participant) no one would solve all 5 problems… except for lim2481284 or shahril (if they actually participate). In terms of balance, we probably need to work on making the difficulty ‘spread out’ more. Additionally, there were some issues with problem C and D.

The problemset can be downloaded through the link above. As usual, for IIUM student, the problems can also be accessed from the IIUM ICPC Team codeforces group. Now, if only they would actually practice, that would be great…. On to the problem analysis!

finalScore
Congratulation to lim2481284 and all participants. Everyone managed to solve at least 1 problem

Needless to say, the participants did well.  The winner of this round is lim2481284 from uniten university who managed to solve 3 problems. Shahril from uitm managed also to solve 3 problems as well, both of them solved A, B and C. However, Shahril was not as fast as lim2481284 and therefore scored the second place. StdLn solved 2 problems, interesting enough he is the only one who solved problem E. It is also interesting to see Foinni who haven’t solved any problem before the freezing of the scoreboard, yet he managed to solve 2 problems in the last hour of the contest rendering him in the fifth place.

Assalamualaikum guys. In this post, I’ll discuss on the question given on IIUM Code Jam 2016.
