Read MoreCount of distinct sums that can be obtained by adding prime numbers from given arrays in C++
We are given two arrays containing prime and non prime numbers. The goal is to find the count of distinct sums of pairs of prime numbers in each array. We will do this by making a pair of two primes from each array, take their sum and add them to set sums. In the end the size of the set is the number of distinct sums of primes. Let's understand with examples. Input Arr1[] = { 1, 2, 3 } Arr2[] = { 2, 3, 4} Output Distinct Sums of primes :3 Explanation Prime pairs ...
Read MoreCount numbers whose difference with N is equal to XOR with N in C++
We are a number N. The goal is to find numbers between 0 and N whose difference with N is equal to XOR with N.We will do this by traversing no. from i=0 to i
Read MoreCount pieces of the circle after N cuts in C++
We are given an integer N which represents the number of cuts applied on a 2D-circle. Each circle divides the circle in two halves. Goal is to find the pieces of the circle after N cuts.Number of pieces= 2 * no. of cutsLet’s understand with examples.Input − N=1Output − Pieces of circle: 2Explanation −Input − N=3Output − Pieces of circle: 6Explanation −Approach used in the below program is as followsWe take N for a number of cuts.Take pieces=1*N.Print the result..Example#include using namespace std; int main(){ int N=2; Int pieces=2*N; cout
Read MoreHow do I change focus to a new popup tab in Selenium?
We can change focus to a new popup tab with Selenium webdriver. The getWindowHandles and getWindowHandle methods are available to handle new popup tabs. The getWindowHandles method stores all the currently opened window handles in Set data structure.The getWindowHandle method stores the window handle of the opened browser in focus. The iterator method is used to iterate over all the window handle ids. We have to add import java.util.Set to accommodate Set and import java.util.List and import java.util.Iterator statements to accommodate the iterator in our code.Selenium driver object can access the elements of the parent window. In order to switch ...
Read MoreHow to wait until an element no longer exists in Selenium?
We can wait until an element no longer exists in Selenium webdriver. This can be achieved with synchronization in Selenium. We shall add an explicit wait criteria where we shall stop or wait till the element no longer exists.Timeout exception is thrown once the explicit wait time has elapsed and the expected behavior of the element is still not available on the page. To check if an element no longer exists on the page, we can take the help of the expected condition invisibilityOfElementLocated.To implement explicit wait conditions, we have to take help of the WebDriverWait and ExpectedCondition class.ExampleCode Implementation.import ...
Read MoreSelenium Web Test Automation Framework Best Practices.
The best practices for Selenium web test automation framework are listed below −Use of dynamic waits like implicit wait and explicit wait instead of using Thread.sleep in the framework to handle sync issues in the application.Usage of Page Object Model framework design to segregate the test scripts from the locators. In case of changes in the webelement properties, test scripts need not be modified only the locators undergo change.Usage of Behavior Driven Development framework. This allows the participation of all members in the agile team to participate in product development.Encourage testing to start from very early phases and in regular ...
Read MoreHow do you click on an element which is hidden using Selenium WebDriver?
We can click on an element which is hidden with Selenium webdriver. The hidden elements are the ones which are present in the DOM but not visible on the page. Mostly the hidden elements are defined by the CSS property style="display:none;". In case an element is a part of the form tag, it can be hidden by setting the attribute type to the value hidden.Selenium by default cannot handle hidden elements and throws ElementNotVisibleException while working with them. Javascript Executor is used to handle hidden elements on the page. Selenium runs the Javascript commands with the executeScript method. The commands ...
