HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, and JavaScript) and span multiple computer science domains. [ 2 ] HackerRank categorizes most of their programming challenges into a number of core computer science domains, [ 3 ] including database management ...
The following sub-projects are located under the Tools sub-project: Buckminster adds support for Component Assemblies. [7] C/C++ Development Tools (CDT) adds support for C/C++ syntax highlighting, code formatting, debugger integration and project structures. Unlike the JDT project, the CDT project does not add a compiler and relies on an ...
Some questions involve projects that the candidate has worked on in the past. A coding interview is intended to seek out creative thinkers and those who can adapt their solutions to rapidly changing and dynamic scenarios. [citation needed] Typical questions that a candidate might be asked to answer during the second-round interview include: [7]
The International Obfuscated C Code Contest (abbreviated IOCCC) is a computer programming contest for code written in C that is the most creatively obfuscated. Held semi-annually, it is described as "celebrating [C's] syntactical opaqueness". [1] The winning code for the 27th contest, held in 2020, was released in July 2020. [2]
With n matrices in the multiplication chain there are n−1 binary operations and C n−1 ways of placing parentheses, where C n−1 is the (n−1)-th Catalan number. The algorithm exploits that there are also C n−1 possible triangulations of a polygon with n+1 sides. This image illustrates possible triangulations of a regular hexagon. These ...
Solution of a travelling salesman problem: the black line shows the shortest possible loop that connects every red dot. In the theory of computational complexity, the travelling salesman problem (TSP) asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the ...
The following program is an implementation of Donald Knuth's informal description of the solution on Page 31, Section 7.2.2 Backtrack Programming from The Art of Computer Programming, Volume 4B into the Python programming language.
