Remove Leading Zeros from an Array using C++
We are provided an array, and we are tasked to remove the leading zeros from the given array and then print the array.Input : arr[] = {0, 0, 0, 1, 2, 3} Output : 1 2 3 Input : arr[] = {0, 0, 0, 1, 0, 2, 3} Output : 1 0 2 3We can make a new array that doesn’t contain the leading zeroes of the previous array in the given problem.Approach to find The SolutionIn this approach, we will go through the array and insert all the numbers but no leading zeros.Example#include using namespace std; ...
Read MoreRemove Last Node of the Linked List using C++
We are provided with a singly linked list, and we are tasked to remove the last node from that list. In this problem, we are simply going to traverse through the given list and simply remove the last node.Approach to find The SolutionIn this approach, we go through the given list, and we keep track of the previous node and the current node. Now when our current node becomes the last node, we change previous -> next to NULL and delete the current node.Example#include using namespace std; struct Node { int data; struct Node* next; }; ...
Read MoreBug Life Cycle in Software Development
We'll go through the life cycle of a defect in this lesson to help you understand the many phases of a defect that a tester must deal with when working in a testing environment.On Defect Life Cycle, we've also included the most often requested interview questions. Understanding the life cycle of a flaw requires knowledge of the many phases of a fault. The primary goal of the testing activity is to see whether the product has any flaws or faults.Errors/mistakes/faults are all known as bugs/defects in real-world circumstances, thus we can say that the basic goal of testing is to ...
Read MoreBoundary Value Analysis & Equivalence Partitioning with Examples
Practically, exhaustive testing for each set of test data is not practicable owing to time and financial constraints, particularly when there is a vast pool of input combinations.We need a simple method or specific approaches for intelligently selecting test cases from a pool of test cases such that all test situations are covered.To do this, we employ two approaches: Equivalence Partitioning and Boundary Value Analysis testing procedures.Software testing, which may be done manually or automatically, is essential for a bug-free program. Manual testing is the most common way for evaluating the functioning of software applications, despite the fact that automated ...
Read MoreBasic Principles of Good Software Engineering Approach
Software engineering refers to the use of systems engineering principles in the creation of software products and applications. It is a discipline of engineering concerned with assessing user requirements, software design, development, testing, and maintenance.The following are some fundamental principles of excellent software engineering −Better Requirement Analysis is a fundamental software engineering technique that provides a comprehensive picture of the project. Finally, a thorough grasp of user requirements adds value to consumers by producing a high-quality software solution that satisfies their needs.All designs and implementations should be as basic as feasible, which implies adhering to the KISS (Keep it Simple, ...
Read MoreAutomation Testing Tutorial for Beginners (Process, Benefits, Tools)
What is Automation Testing and How Does It Work?Automation Testing, often known as Test Automation, is a software testing approach that involves the execution of a test case collection using particular automated testing software tools. On the other hand, manual testing is carried out by a person sitting in front of a computer, methodically carrying out the test processes.In addition to entering test data into the System Under Test, the automated testing software may analyze predicted and actual outcomes and provide complete test reports. Software Test Automation necessitates significant financial and human resources.Continuous implementation of the same test suite will ...
Read MoreApplication Testing Tutorial (What is, How to, Tools)
What exactly is application testing?Application testing is a sort of software testing that is carried out using codes with the goal of detecting faults in software. It is concerned with testing the complete application.It aids in improving the performance of your products as well as lowering expenses, increasing ROI, and shortening production time.Application testing may be conducted in several areas such as GUI, functionality, database (backend), load test, and so on.The testing phases for application testing comprise stages such as requirement analysis, test strategy, test analysis, test plan, test execution, and issue management, among others.You will learn the following in ...
Read MoreAPI Testing Tutorial for Beginners
What is an API?An API (Application Programming Interface) is a computer interface that allows two different software systems to communicate and share data. A software system that performs an API has numerous functions/subroutines that may be performed by another software system. Between two software systems, an API describes the types of requests that can be made, how they may be made, the data formats that can be utilized, and so on.Shift Left TestingShift Left Testing is one of the most common forms of testing that is now being asked in API Testing Interviews. Almost every project that follows the Agile ...
Read MoreAgile Methodology and Model
What is Agile Methodology?The term "agile methodology" refers to a process that encourages continuous development and testing throughout the project's software development life cycle. Unlike the Waterfall paradigm, both development and testing operations are contemporaneous under the Agile style of software testing.Agile Methodology Vs. Traditional Software DevelopmentOne of the easiest and most successful ways to transform a vision for a company requirement into software solutions is to use the Agile software development approach. Continuous planning, learning, improvement, team collaboration, evolutionary development, and early delivery are all terms used to define agile software development methodologies. It increases adaptability in the face ...
Read MoreRemove First Node of the Linked List using C++
Given a linked list, we need to remove its first element and return the pointer to the head of the new list.Input : 1 -> 2 -> 3 -> 4 -> 5 -> NULL Output : 2 -> 3 -> 4 -> 5 -> NULL Input : 2 -> 4 -> 6 -> 8 -> 33 -> 67 -> NULL Output : 4 -> 6 -> 8 -> 33 -> 67 -> NULLIn the given problem, we need to remove the first node of the list and move our head to the second element and return the head.Approach to ...
