Volume 1. ICPC World Finals Problem Index. Articles | ACMSolver. By DmitryKorolev (collected from Topcoder) ContainersBefore we beginVectorPairsIteratorsCompiling STL ProgramsData manipulation in VectorStringSetMapNotice on Map and SetMore on algorithmsString StreamsSummary Perhaps you are already using C++ as your main programming language to solve TopCoder problems. This means that you have already used STL in a simple way, because arrays and strings are passed to your function as STL objects. You may have noticed, though, that many coders manage to write their code much more quickly and concisely than you. Or perhaps you are not a C++ programmer, but want to become one because of the great functionality of this language and its libraries (and, maybe, because of the very short solutions you’ve read in TopCoder practice rooms and competitions).

Regardless of where you’re coming from, this article can help. The simplest way to get familiar with STL is to begin from its containers. For example, we may need one or more of the following operations: Problems. SVDLIBC. A C Library for Computing Singular Value Decompositions version 1.4 SVDLIBC is a C library written by Doug Rohde. It was based on the SVDPACKC library, which was written by Michael Berry, Theresa Do, Gavin O'Brien, Vijay Krishna and Sowmini Varadhan at the University of Tennessee.

SVDLIBC is made available under a BSD License. SVDLIBC offers a cleaned-up version of the code with a new library interface and a front-end executable that performs matrix file type conversions, along with computing singular value decompositions. Installing To install SVDLIBC: Click here to download the tar file.To unpack the tar file run this on the command-line:tar xvzf svdlibc.tgz cd SVDLIBCYou may want to edit the Makefile to use your favorite compiler. Command-line Interface The command-line interface, svd, allows you to perform an SVD on a matrix, optionally storing the left- and right-singular vectors and the singular values in separate files. C Library Interface The library defines three structures.

CS 97SI: Introduction to Competitive Programming Contests. Course Information and Announcements Instructor: Jaehyun ParkStanford ACM-ICPC Coaches: Jaehyun Park, Andy Nguyen, Jerry Cain(Added on 8/21/2013) This class was taught in 2011-12 Winter. I'm getting a lot of emails asking if I'm teaching it again, but there is no plan to offer the course at the moment.

Lecture slides Practice Problems All the problems below are from Peking Online Judge (POJ). Problems are classified into 10 different categories, and the lectures will cover essential algorithms and theoretical background for each particular category. The numbers in parentheses represent the difficulty of the problems (0: easiest, 10: hardest). Common coding mistakes Not initializing variablesUsing 32-bit integers instead of 64-bit onesUsing out-of-bound array indicesUsing a semicolon after a for loop for(i = 0; i < n; i++); some code Reusing the same variable in nested for loops for(i = 0; i < 1000; i++) for(i = 0; i < 10; i++) some code #define min(a, b) a<b?
