TCO10 Qual 3 Easy - SumRectangle by jbernadas

This video features me solving the easy problem from TCO10 Qual 3 round, called SumRectangle. The problem is really easy, basically I want to show how do I use my enviroment during contests in TopCoder. You can see I use CodeProcessor, FileEdit and moj to run my TopCoder tests locally.

Also, I use Windows 7 profession 64 bits, Visual Studio 2010, a 1920x1200 monitor (with the laptop 1600x900 at a side), and a home-made add-in to expand code inside the editor.

Actually, I'm not rated coder but member I think, since 2008. I don't have available time to compete in rated events. Always solving the problems in practice rooms.

@proton101 I should go back to solving problems in the practice rooms, I'm getting rusty.

I'm using FileEdit but I do not know how to use all the functionality of that add-in.

What's the best editor for C#? My default programming language is C# but I can also work with Java. Thanks.

[jbernadas]

@proton101 For C#? Probably Visual Studio. The problem is that, as far as I know, there is no equivalent to moj or TZTester in C#, which is the most important part of using these plugins.

@rubedu86 Nice, 2 problems in division 2 is a good start. To improve just practice a lot in the arena, solve old problems and read the editorial only if you get stuck. Also, SPOJ is another good site to practice. Practice is the key.

About books, I've only read the second part of Algorithms in C, it helped me a lot for graphs. Also, I was reading Concrete Mathematics and Introduction to Algorithms, but I don't have that much free time anymore.

@proton101 I can't help you there, I've never used KawigiEditor.

[jbernadas]

@proton101 Sorry, I didn't see your comment until now, that somebody else commented and took a look at the comment section. The answer is no, when I submit my code it doesn't include the test code with the test cases, so I don't lose points because of UCR.

[jbernadas]

@proton101 No, everything between the "// BEGIN CUT HERE" and "// END CUT HERE" lines is stripped out from the source code before sending it to the TopCoder Arena, so there is no risk of a UCR penalty because of the test harness.

[proton101]

@jbernadas

BTW, when you pass your solution, do the plugin will also pass together with your test code like on your video?

@jbernadas

Thanks. I'm using KawigiEdit as my text editor but other functionalities of that plugin gives me errors.
