Suppose we have a non-negative index k where k ≤ 33, we have to find the kth index row of Pascal's triangle.So, if the input is like 3, then the output will be [1,3,3,1]To solve this, we will follow these steps −Define an array pascal of size rowIndex + 1 and fill this with 0for initialize r := 0, when r
We can get the value of the edit box in Selenium by the following ways −By using getText () method.Using the class JavascriptExecutor.Code Implementation with method getText ().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 GetValueScripting { 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); driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS); String text = driver.findElement(By.className("gsc-input")).getText(); System.out.println("Extracted text is " + text); driver.close(); ...

Suppose we have a binary tree; we have to find the minimum depth of that tree. As we know the minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node.So, if the input is likethen the output will be 2To solve this, we will follow these steps −Define an array aa of tree nodesinsert root at the end of aaDefine another array ak of tree nodeslevel := 0if root is null, then −return 0while size of aa is not equal to 0, do −clear the array ak(increase level by ...

Suppose we have two binary trees; we have to define a function to check whether they are the same or not. We know that the binary trees are considered the same when they are structurally identical and the nodes have the same value.So, if the input is like [1, 2, 3], [1, 2, 3], then the output will be TrueTo solve this, we will follow these steps −Define a function called isSameTree, this will take two tree nodes p and qif p is the same as NULL and q is same as NULL, then −return trueif p is the same ...

We can enter text in the edit box in Selenium by the following ways −By invoking sendkeys() method.Using the class JavascriptExecutor.Code Implementation with sendkeys() method.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 TextEnter { 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); driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS); driver.findElement(By.className("gsc-input")) .sendKeys("Selenium"); driver.close(); } }Code Implementation with class JavascriptExecutor method.Exampleimport org.openqa.selenium.By; ...

Suppose we have a sorted linked list; we have to delete all duplicates such that each element appears only once.So, if the input is like [1, 1, 2, 3, 3, 3, 4, 5, 5], then the output will be [1, 2, 3, 4, 5]To solve this, we will follow these steps −dummy := make a new node with value -infnext of dummy := headcurr = dummywhile curr is non-zero, do −next = next of currwhile (next is not null and val of next is same as val of curr), do −next := next of nextnext of curr := nextcurr := ...

Suppose we have a string s. s can hold any English letters and white-spaces. We have to find the length of last word in the string. If there is no last word, then return 0.So, if the input is like "I love Programming", then the output will be 11To solve this, we will follow these steps −n := 0for each word temp in a string −n := size of tempreturn nExampleLet us see the following implementation to get a better understanding − Live Demo#include using namespace std; class Solution { public: int lengthOfLastWord(string s){ stringstream str(s); ...

The most basic steps to write a web driver script are listed below −Open any browser by creating a webdriver reference pointing to the corresponding browser driver class.Launch any URL with the get() method.Pause for some time for the page load.Confirm that we are on the correct web page.Finally close the session.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; public class WebScripting { 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"; ...
