Knot is a network server as well as Haboob. The difference is the concurrency model: Knot is thread-based, instead Haboob is event-based [9]. Clearly, from the benchmark results, the poll()/epoll() mechanism is a serious bottleneck as soon as the number of active concurrent clients become relevant (in the specific case, at 16384 clients the trashing… Continue reading Scaling to Thousands of Threads

Puzzle Given an Unsorted Single Linked List, provide an Algorithm to reverse such Linked List using only 2 pointers. Input A Single Linked List. Example. 1 -> 4 -> 3 -> 2 -> 0 Output A Reversed Single Linked List. Example. 0 -> 2 -> 3 -> 4 -> 1 Solution Using Java as… Continue reading Coding: Reversing Unordered Single Linked List using 2 Pointers
Puzzle Given an array of Integers that presents several levels of nesting, provide an algorithm to flatten the input array. Input A nested array of arrays. Example. [[1,2,[3]],4] Output A flat array. Example. [1,2,3,4] Solution using Java as Programming Language Gist with runnable code and tests. Discussion To get the job done, the solution adopts… Continue reading Coding: Flattening Nested Arrays
