Every so often its good to exercise your brain with a math problem or two that forces you to recall principles you learned ...

A combined cryptosystem with symmetric keys for encrypting messages is proposed. Its unique feature is the use of functions of a real variable as keys instead of natural numbers. Eight key functions ...

Introduced in Java 5, generics enhance the type safety of your code and make it easier to read. This helps you avoid runtime errors like the ClassCastException, which happens when you try to cast ...

The incubating Java Vector API gives software developers access to fast and efficient SIMD operations. Here's an example of how to solve the prefix sum problem with SIMDs and Vectors.

What is the prefix sum array problem? The prefix sum problem in computer science is a popular programming puzzle used to test the array handling skills of software developers. The prefix sum problem ...

First line of input contains T - the number of test cases. Its followed by 2T lines, the first line contains N - the size of the array. The second line contains the elements of the array. For each ...

In this paper, direction of arrival (DOA) estimation using sum co-array of coprime arrays is studied. The array geometry can be represented as the kronecker product of those of two coprime arrays.

Arrays are a popular data structure used in programming for storing multiple values of the same data type. Often times, when working with arrays, we may want to find the sum of all the elements in the ...

Use ForkJoinPool to break down computationally intensive tasks and execute them in parallel for better Java application performance.
