Did you ever need to configure Maven dependency to local JAR? It’s rarely needed, but when it is, it’s good to know how to do that correctly.
One of the simplest cryptographic algorithms is Caesar cipher. It’s not really secure, but sometimes you may encounter it in some exercises or crackmes.
As many other algorithms in Linked List – remove element from given position runs in linear time. Here we are going to implement it to better understand how it works.
In this post we’ll implement another algorithm for Linked List – insert element at position. The algorithm works in linear time in the worst case.
Linked List is a simple data structure. Implementing it from scratch helps to understand its properties. We’ll implement Linked List add, size, and print its contents.
One of the best known algorithms to detect a cycle in a linked list is Floyd Cycle detection. Using Floyd’s algorithm we can detect cycle, its beginning, and length.
Palindrome is a sequence of chars which reads the same backward and forward. Detecting palindrome is a common job interview task therefore we’ll show how to implement that.
Shuffling of arrays/lists sounds like a trivial task, but in reality it’s full of subtle traps. Here we show how to implement Fisher-Yates Shuffle Algorithm in Java.
Divide and Conquer algorithms are great subject for parallelism. Here we present Parallel Merge Sort implemented using Java ForkJoin Framework.
In this post we’re going to implement calculation of Greatest Common Divisor GCD in Clojure using Euclidean algorithm for two and more numbers.
