Analysis of different sorting techniques

In this article, we will discuss important properties of different sorting techniques including their complexity, stability and memory constraints. Before understanding this article, you should understand basics of different sorting techniques (See : Sorting Techniques).  Time complexity Analysis – We have discussed the best, average and worst case complexity of different sorting techniques with possible scenarios.  Comparison based sorting – In comparison based sorting, elements of an array are compared with each other to find the sorted array.    Bubble sort and Insertion sort – Average and worst case time complexity: n^2 Best case time complexity: n when array is already sorted. Worst case: when […]

Implementing the Flip Algorithm For Non-Delaunay Triangles in Java

In computational geometry, the Delaunay triangulation is a fundamental concept used to partition a set of points into a mesh of non-overlapping triangles with the property that no point lies inside the circumcircle of any triangle. However, in certain cases, we may encounter non-Delaunay triangles where this property is violated. In this article, we will explore the Flip Algorithm, a technique used to transform non-Delaunay triangles into Delaunay triangles by flipping edges. We will implement the Flip Algorithm in Java and provide examples to illustrate its functionality. Technical Components To implement the Flip Algorithm for non-Delaunay triangles, we need to […]

Review: The OnePlus 13R will make you forget you’re using a sub-$600 phone

Everyone loves a comeback story. Just three years ago, OnePlus was in a weird place. OxygenOS 12 was a mess, and the company was trying to integrate elements of ColorOS into the user experience. In addition, OnePlus’ hardware had lost its identity, veering way off course with the OnePlus 9 and 10. However, when I used the OnePlus 10T, I felt a glimmer of hope that some of the old OnePlus was still with the company. Sure enough, each successive release has been better than the last. While the OnePlus 13 is getting heaps of praise, and rightfully so, I […]

Priority CPU Scheduling with different arrival time – Set 2

Prerequisite – Program for Priority Scheduling – Set 1Priority scheduling is a non-preemptive algorithm and one of the most common scheduling algorithms in batch systems. Each process is assigned first arrival time (less arrival time process first) if two processes have same arrival time, then compare to priorities (highest process first). Also, if two processes have same priority then compare to process number (less process number first). This process is repeated while all process get executed. Implementation –  First input the processes with their arrival time, burst time and priority. First process will schedule, which have the lowest arrival time, […]

Spring Boot Interview Questions

Spring boot is a Java-based spring framework used in Java Application development. Spring Boot is a microservice-based framework that makes a production-ready Java application in very less time. Spring is fast, has a low configuration, an inbuilt server, and monitoring features which help to build a Java application very fast from scratch with robustness and maintainability. We just need to use the proper configuration for utilizing a particular functionality because most of the functionalities are auto-configured. Spring Boot is very beneficial if we want to develop REST API. It also has extra support for embedded application servers like Tomcat, Jetty, […]
