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.
Caesar cipher in Java
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.
Linked List – remove element
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.
Linked List – insert element at position
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 add element at the end
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.
Floyd Cycle detection in Java
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 detector in Java
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.
Shuffle Algorithm in Java
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.
Parallel Merge Sort in Java
Divide and Conquer algorithms are great subject for parallelism. Here we present Parallel Merge Sort implemented using Java ForkJoin Framework.
GCD in Clojure using Euclidean algorithm
In this post we’re going to implement calculation of Greatest Common Divisor GCD in Clojure using Euclidean algorithm for two and more numbers.
