ZCO 2017 Discussion

general
36

I gave ZCO in Kolkata. The second problem solved in roughly 20-30 minutes. Though it wasn’t because of the terrible application of TCS. Dev-CPP terminal was getting closed within 5 seconds. I changed my system 3 times. My code was a little bit wrong. What I did was that I hard coded my test case into my program in DevCPP. Finally, I was able to solve problem number 2 and it was accepted correctly. Due to these terrible situations, I couldn’t get time to do the first problem.

Dear Student,

You attended ZCO-2017 on Sunday, 20 November, 2016. Several ZCO
centres experienced technical difficulties with the TCS iON
platform, as a result of which a large number of students did not
get a fair chance to attempt the exam. Hence, we have decided to
allow all students who were present for ZCO on 20 November to
directly write the second round exam, INOI.

INOI-2017 is scheduled for Sunday, 8 January, 2017. We are in the
process of reviewing the technical arrangements for INOI. We will
send out details about the final platform in a few days.

I wrote ZIO this year. I didnt face any problem…But not all ZCO candidates must be selected for INOI.
This is an unfair decision and will affect a lot of ZIO candidates also. A re-exam must be conducted and only those who do well should be selected…I find this very unfair.

I think IARCS should seriously look into making sure that INOI does not face the same problems.If it is possible, please request the IARCS committee to either change their system or host it on some online judge like Codechef. Codechef even hosted the ICPC regionals so it should be fine to host INOI on it.

The server not responded and the PC shutdown many times we got only 15 mins in total and all other time we sitted their.

41

Oh… That’s is really awful… :frowning:

42

Same as above, I had to change about 20 times barely even got the chance to code. Couldn’t submit solutions either :confused:

Btw, I too was able to solve only the first question… :frowning:

44

I remember one i will try posting it soon. Btw how was your ZIO @mathecodician?

45

I knew to solve every problem but just too many careless mistakes. I dunno I think I will get like 55. Hope I qualify as I’m in class 8.

In last one hour I wasn’t able to open Dev C++ even very bad thing

Lasers travel towards right and even if it encounters a black box after a white box it stops.

48

Why do you say unfair?

49

What about those who didn’t qualify for INOI? If they would have given ZCO they could have been selected without any effort. I suggest a retest

50

I guess the first one was to be done in n^2. I did not give ZCO although so I am not sure. Maybe n^2 log n solution would also work.

51

Btw, how did you solve the 2nd problem was your solution quick enough for the 3rd subtask?

52

The SUMFOUR problem seems to be a bit different as the four integers have to be from the 4 different sets. So the first one, was much easier. Thanks @mathecodician

53

But still there is little bit similarity.

54

Last year, ZCO was a huge mess, but INOI was much better. The Kolkata center was pretty much bug-free. They gave us extremely slow machines but it was manageable for INOI purposes.

Let’s hope you guys get similar arrangements for INOI.

55

I think they should do it on codechef only as we are all familiar with the platform.
