Hi Friends,
Anyone know if there is a plugin somewhere for C++ so I dont have to write all the boiler plate iostream code? Or is writing Cin apart of the contest?

Looking at your code, I think the main issue is just that you're doing input in a weird way. Usually, people just use cin for everything.
For example, look at one of my solution's inputs compared to yours.

You kinda write input like you're using Python.
Thanks for the reply Chili.
I write in that style too (Using CIN). But sometimes when the input is too large, CIN doesnt work, and I have to use getline().
In today's contest, I think I spent over 50% of time getting my IO to work. It was the most frustrating thing ever. Hopefully I can speed it up next time... Sigh...
I've almost never had issues with cin being too slow, assuming you have sync_with_stdio stuff. The only times I ever need get_line are when I seriously need the entire line, and not just one word/number.
Could you give an example of a problem where you had issues just directly using cin?
Hey Chilli,
I am working on the marathon this week. These are my submissions http://codeforces.me/contest/1014/my
For this submission, CIN didn't work for me. I think because the input was too long, 100 000 chars in total in 1 line. http://codeforces.me/contest/1014/submission/40719388
So I changed it to getline() here and it worked. http://codeforces.me/contest/1014/submission/40757115
I can't view those submissions since marathon is an ongoing contest.

it's ongoing contest, don't discuss
Always add this at the beginning of
main:I personally use this when competing. This makes I/O a lot faster.
I will. Any reasons why?
Thanks Ivan.
It was kind of hard for me to figure out what was going wrong with your submission before, but I doubt it was related to cin; you don't usually get runtime errors from stuff like that.
As for why you should use the things above, cin/cout by default synchronize their buffers with scanf/printf. This makes them a lot slower. The first one is the most important, the second is often just tossed in there, and I don't actually use the third line.
