Brushing up your array knowledge is of utmost importance especially if you are a programmer! So today, we are going to discuss arrays, its related  concepts like array rotation  and its key benefits to the programmer. An array is a data structure to store a specific data type. However, you need to know that an array has a definite size. This means that you will have to assign a certain memory to an array, depending upon the data type.  For better understanding, consider an array as a collection of elements of a similar type. So, if you are storing an integer in an array, you can only store an integer in that array. You can not store character, float, or any other data type in an integer array. Other than this, arrays are single-dimensional and multidimensional that you can use according to your requirement. There are different advantages associated with an array including reducing the code and reducing memory usage.  Read on to know about these advantages in ...

  While doing programming, there are thousands of things you have to remember and keep in your mind at all times.  How would you feel if you have a messed-up path on which you have to run your program or code to reach the destination or output? Quite obviously, Not great.  However, algorithms will save the day for you on this one.But do you know what the term algorithm means in computer networking Algorithms are defined as a simple step-by-step explanation of the path on which your program will run. Whereas in the more technical world or simply programming, the algorithm is stated as a unique procedure that considers specific values as inputs and others as output to generate a computed path for a program.  There are many  factors such as the time complexity of sorting algorithms , their working, efficiency, and much more that you need to understand while working with the algorithms. However, among these, the most important factor is to understand why algorithms ...

  Recruitment refers to actively seeking out and hiring the most suitable candidates for a specific position or job. Whenever we want to define recruitment, it should include the entire hiring process, from inception to the individual recruit's integration into the company. Recruitment identifies and entices potential employees to fill open jobs in a company. It is a process of identifying applicants who possess the skills and attitudes necessary to help a business achieve its goals. To evaluate candidates on a better scale, most companies also conduct online assessment tests like Goldman Sachs online assessment tests, TCS code vita etc. These tests are often just round 1 of the recruitment process.

  Introduction  In this article, we will learn about Detect Cycle in Directed Graph  using multiple approaches.  Examine a directed graph to see if it has a cycle. If the given graph contains at least one cycle, your function should return true; otherwise, it should return false. Method 1: DFS Approach A cycle in a graph can be detected using Depth First Traversal. A tree is produced using DFS for a connected graph. Only if the graph has a rear edge does it have a cycle. A back edge in the DFS tree is an edge that connects a node to itself (self-loop) or one of its ancestors. Get the DFS forest as output for a disconnected graph. Check for a cycle in individual trees by looking at the back borders. Keep track of the vertices currently in the recursion stack of the DFS traversal algorithm to detect a back edge. There is a cycle in the tree if a vertex is reached that is already on the recursion stack. A back edge connects the current vertex to the next verte...
