Suppose we have a pattern and a string str, find if str follows the same pattern. Here follow means there is a bijection between a letter in pattern and a non-empty word in str.So, if the input is like pattern = "cbbc", str = "word pattern pattern word", then the output will be True.To solve this, we will follow these steps −strcin := strDefine an array of wordsfor each word in strcininsert word at the end of wordsDefine one map p2ii := 0pat := empty stringfor c in pattern −if c is not member of p2i, then −(increase i by ...

The relative or friendly locators in Selenium 4.0 are available with the tagname attribute of the element.above() - Webelement located above with respect to the specified element.Syntax −driver.findElement(withTagName(“”).above(element));below() - Webelement located below with respect to the specified element.Syntax −driver.findElement(withTagName(“”).below(element));toLeftof() - Webelement located to the left of the specified element.Syntax −driver.findElement(withTagName(“”).toLeftOf(element));toRightOf() - Webelement located to the right of the specified element.Syntax −driver.findElement(withTagName(“”).toRightOf(element));Code Implementation with relative Locators.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import static org.openqa.selenium.support.locators.RelativeLocator .withTagName; public class RelLocator { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver ...

Suppose we want to implement one stack using a queue. We have to define these methods for the stack.push(x) − Push x onto stack.pop() − Delete and return top element from stacktop() − Return the top element from stack.empty() − Return whether the stack is empty or not.So, if we call the functions push(10), push(20), then call pop(), pop(), then the output will be 20, 10To solve this, we will follow these steps −Define one deque qDefine a function push(), this will take x, insert x at the beginning of qDefine a function pop()k := first element of qdelete front ...

The various important exceptions in Selenium are listed below −TimeOutException − This exception is thrown if an action does not complete in a particular duration. If the page element does not load even after the waits.driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS) ; driver.get(“https://www.tutorialspoint.com/index.htm” );In the above program, an implicit wait of 15 seconds is added. If the page https://www.tutorialspoint.com/index.htm doesn’t load in 15 seconds, then TimeoutException will be thrown.NoSuchElementException − This exception happens if the web element with particular attributes does not exist on the page. This exception class is a subclass of NotFoundException and is thrown if the driver is not successful in ... Read More
Suppose we have an array and an integer k, we have to check whether there are two distinct indices i and j in the array such that nums[i] = nums[j] and the absolute difference between i and j is at most k.So, if the input is like [1, 2, 4, 1] and k = 3, then the output will be TrueTo solve this, we will follow these steps −Define an array nn of pairsfor initialize i := 0, when i − size of nums, update (increase i by 1), do −insert {nums[i], i} at the end of nnsort the array ...

The different cookies method in Selenium are listed below −driver.manage().deleteAllCookies() − This removes all cookies.driver.manage().deleteCookie(Id) − This removes a particular cookie.driver.manage().deleteCookieNamed(CookieName) − This removes a particular cookie based on Name.driver.manage().getCookies() − This returns all the cookies.driver.manage().getCookieNamed(CookieName) − This returns a particular cookie based on Name.driver.manage().addCookie(Id) − This adds a particular cookie.Code Implementation with some cookies method.Exampleimport org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class CookiesScripting { public static void main(String[] args) { // TODO Auto-generated method stub System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); driver.manage().window().maximize(); // ...

Suppose we have two strings s and t; we have to check whether they are isomorphic or not. Two strings are said to be isomorphic if the characters in s can be replaced to get t.All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same character but a character may map to itself.So, if the input is like s = "egg", t = "add”, then the output will be true, as e can map to a, and g can map to d.To solve this, we ...

We can maximize the browser in Selenium with the help of method maximize().The present active window becomes maximized with this method.Code implementation.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class BrowserMax { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://www.tutorialspoint.com/index.htm"; driver.get(url); // maximizing browser with maximize() driver.manage().window().maximize(); driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); driver.findElement(By.partialLinkText("Coding")).click(); driver.close(); } }Read More
Suppose we have a positive integer; we have to find its corresponding column title as appear in an Excel sheet. So [1 : A], [2 : B], [26 : Z], [27 : AA], [28 : AB] etc.So, if the input is like 28, then the output will be AB.To solve this, we will follow these steps −while n is non-zero, do −n := n - 1res := res + n mod 26 + ASCII of 'A'n := n / 26reverse the array resreturn resExample Let us see the following implementation to get a better understanding − Live Demo#include using namespace std; ...

getWindowHandle() and getWindowHandles() methods have some prominent differences.driver.getWindowHandles() – It stores the set of handles for all the pages opened simultaneously.driver.getWindowHandle() – It fetches the handle of the web page which is in focus. It gets the address of the active browser and it has a return type of String.Code ImplementationExampleimport org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.Set; import java.util.Iterator; import org.testng.annotations.Test; public class WindowHandles{ @Test public void windowHandle() throws Exception { System.setProperty("webdriver.chrome.driver", "C:\Selenium\chromedriver.exe"); WebDriver driver = new ChromeDriver(); driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); ...
