As we have discussed before in the posts, threads and processes are a bit different concepts. The difference between threads and processes in terms of memory management is that threads within one process run in a shared memory while processes run in a separate memory. There are two types of…

Thread life cycle In Java, a thread passes four states during its life cycle: - New - Running - Waiting — [Blocked, Waiting, TimedWaiting] - Dead New — when a thread is instantiated and ready to use. It is the state when we have not started the thread yet. Running — a thread enters…

The terms of process and threads are commonly used when it comes to multithreading. In this post, we will explore these concepts in detail and many more.

No matter what language you use to write your programs, they are all sequential by default. That is, all the instructions we write are executed line by line by the operating system. The next line of code cannot start execution before the current finishes and waits until the current line…

Sql just like any other programming language provides functions and stored procedures. In this post, we will explore the functions and stored procedures in PostgreSQL. …

A double-ended queue, or Deque, is a linear collection of data that takes the concept of Queue into a step further. Deque is very similar to Queue, however, it complements Queue with some more useful operations. Deque allows adding items to both ends and removing items from both ends as…

Competitive programming combines two topics: the design of algorithms and the implementation of algorithms. Design of Algorithms. The core of competitive programming is about inventing efficient algorithms that solve well-defined computational problems. The design of algorithms requires problem-solving and mathematical skills. …

Queue is a linear, or sequential, collection of items that is very similar to Stack but with few differences. As it is clear from its name, it functions as a real queue. …

Stack is a linear, or sequential, collection of data that are, as the name says — stacked, or put on top of each other. Stack is one of the most fundamental and earliest-developed concepts in Computer Science. The idea of Stack is pretty straightforward, yet it has been very efficient…
