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 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 ...
