What do all of you think about ZCO will it be Reorganized or all who participated in ZCO will be entitled for INOI?

I frequently got disconnected saying āYour session has been expiredā. I had to change about 5 computers during the exam. Also, I couldānt run my test cases in DevC++ā¦ The output window closes itself even before I gave the input. 
I request all those who had faced technical issues to mail IARCS reporting them about the sameā¦
FLASH NEWS!!
All those who were present for ZCO 2017 are eligible for INOI 2017.

The server not responded and the PC shutdown many times we got only 15 mins in total and all other time we sitted their.
Ohā¦ Thatās is really awfulā¦
I gave ZCO in Kolkata .It was PLAIN HORRIBLE.
I thought about the problems for about 30 minutes : was able to find a complete solution to the second problem and the first two sub-parts of the first problem. However, the problems started when I started to code. The dev-cpp closed one time and all the code was lost. Once the computer hanged and some time was wasted.And the MOST MAJOR PROBLEM was that I could not test my program on the dev-cpp as every time I tried to run the code, the command-prompt mysteriously closed within 5 seconds, EVEN IF I DID NOT TOUCH THE KEYBOARD. The result was that I could only submit the solution to the server and hope for the best and try to discern my flaws from the input and the expected output. As a result, I could only get the first two sub-tasks correct of the first problem and got 0 in the second one, even though I had solved it soundly.
I have already mailed IARCS about this and I would suggest all those whose exam went badly due to technical errors to do the same.

HORRIBLE is the only word for TCS ION, Iām sure IARCS worked pretty hard but TCS ionās shitty system put it all in the vain.
Almost everybody at the Indore centre got disconnected >=3 times during entire examination, Lets hope thereās justice to everybody.
Fingers Crossed.
Same as above, I had to change about 20 times barely even got the chance to code. Couldnāt submit solutions either

The experience at Patna was totally horrible. The questions were extremely easy and both could be solved in approximately 1.5 hours. I had to change my PC 4 times. At intervals of 15-20 mins, my computer got disconnected from the network saying āSession Expired.ā The main problem was copying and pasting the code. Right click was prohibited and whenever I used the keyboard to paste my code, my PC got locked. I too got the first two sub-tasks totally correct of the first question correct and 0 for the second one, although I had solved it correctly.
I would request everyone who has experienced these kind of problems to mail IARCS.
Btw, I too was able to solve only the first questionā¦
There were problems in ZIO also.
The computers closed at any random point. (closed about 4 times for me)
The keyboard was not working so I had to use the mouse to type the answers and also for using the calculator. It was then very difficult to use calculator as I had to click like 5 times to enter a number because the mouse also was not very good.
But after looking at the problems faced by the ZCO people, I should say that ZIO was Ok.
Can someone give the problems?
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 Iām in class 8.

I gave the ZCO from Pune and it was a horrible experience. Had to change my pc 8 times.However I had a word with Madhavan Sir, he said we need to mail the problems we faced so that the can find a solution
I participated in ZCO chandigarhā¦ The 2nd problem was quite challengingā¦ My computer crashed once ā¦ It was very difficultā¦ And new format of 3 subtasks was insaneā¦ Letās hope for the bestā¦ Anyone who was able to solve 2 problem please let me know how to solve that. And I donāt know why my 6 cases were not correct in subtask 3 of problem 1 please helpā¦

In my opinion, ZCO 2017ās experience was worse than the previous yearās. The console problem hampered my performance throughout, I couldnāt input custom test cases nor could I know what my program was outputting. All I could hope for was the feedback of the judge which was very slow and took as much as 5 mins to respond and during that time I could not even go back to the IDE! The problems were fairly easy but debugging my code for them was a nightmare, without the output console I had to rely on the age old read-through-your-program method(which is often not useful). A couple of times the judge threw a compile time error saying ābits/stdc++.hā is unrecognised even though it worked perfectly on the other subtasks! I gave ZCO in the Kolkata centre where the invigilators were very ignorant regarding the problems we faced and literally scolded us for testing the IDE before the exam began!! I really hope IARCS shifts their platform to codechefā¦ It would be so perfect!
I am going to mail the authority regarding the issues and hope they will figure a way out.

- I had to change my PC 13 timesā¦ However Problems were too easyā¦
- First Subtask: Full/Full
- In Second :FULL/FULL
- In third : 21/30 therefore 20 marks gone from here
- In fourth :Full/FUll
- In fifth : 23/32 therefore 50 marks gone from here
- In Sixth :Too much time was taken in compilation and hence in submission but still I Feel It will be a timeout. therefore 40 marks gone fromhereā¦
Someone with better time complexity please tell the solutions
In last one hour I wasnāt able to open Dev C++ even very bad thing
Guys, The devcpp was not giving output and automatically closing due to which i had added an extra cin which did nothing just to see the input.
