Most of us must have registered for TCS CodeVita, this was my experience for yesterday’s Zone 2 Pre-qualifier Round:

I started in early hours of the contest. Tried 2 problems but couldn’t get AC. After spending almost 2 hours, I checked the Graphs section, at that time only 2 problems had submissions which were either Accepted or had Presentation Error, I solved those two problems in about an hour.

Then I checked the graph again, still the condition was same and I was like, *one more problem and I will be on TOP.* **Hell yeah!!! **

Later, in an hour, I realised that I was not **spending** time, but I was actually **wasting** time on those problems. I checked the graph, it showed over 2500 unaccepted, but no accepted solution yet. I mailed them regarding the same, and they replied: *“The problems have been thoroughly tested. Please check your solution.”*

Remaining two problems had no accepted submissions too, so considering the situation then, I assumed that those were **thoroughly tested** too, and decided to quit. Most probably, others must have assumed the same, since there were not so many submissions at that time. But when I checked the graph in the last 5 minutes, there were some **Amoeba sized bars** of presentation error verdict (for the remaining two ~~problems~~ questions).

Hats Off to the TCS CodeVita Season 9 Setting Team *(& Testing team too, if they exist)*

Thank You for such a great, I mean not so great Contest. *(flow flow me great likh diya )*

**How was your experience? And I would really like to hear other’s thoughts on the same.**

P.S, My set had Following ~~problems~~ questions:

Fill the Cube

Odd Even

Max Sum

Path through Graph

Equalise Weights

3 Palindrome

The two **thoroughly tested** problems were **Fill the Cube** and **Odd Even**.

Since the contest is over, if anyone had some common problems and were able to solve them, then please share your approach.
