Smoke Testing:- It’s done at the early phase of software development life cycle to ensure that core functionalities are working fine. The main purpose to identify the blocker or any major issues at the very early stages to save the efforts and time of the delivery life cycle. Sanity Testing:- It’s performed when a new…
So for that at first we have to set the system property “webdriver.chrome.driver” and need to provide the path of the executable file of the chrome driver. The code block is mentioned below:- Now we can set the options of the chrome driver. This step is optional. Here we can set the execution mode of…
Many times we have to handle the suggestions in the search box dynamically. As shown below for the google search page. When typed “selenium” word, it’s showing so many suggestions:- Now if we want to select only “selenium interview questions” then how to do that? As these options appears dynamically, so by using fixed locator…
Merge Sorted Array solution in java You are given two integer arrays nums1 and nums2, sorted in non-decreasing order, and two integers m and n, representing the number of elements in nums1 and nums2 respectively. Merge nums1 and nums2 into a single array sorted in non-decreasing order. The final sorted array should not be returned…
Two Sum Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. This problem is…
Maximum Subarray Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. A subarray is a contiguous part of an array. The problem is taken from the below mentioned link:- Leetcode Problem Approach:- In most of the case this kind of problems…
Contains Duplicate Given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct. The above problem is taken from the below mentioned link:- Leetcode Problem Approach:- Use of HashSet data structure will solve the problem. Here Set is chosen as it…
Convert Binary Number in a Linked List to Integer Given head which is a reference node to a singly-linked list. The value of each node in the linked list is either 0 or 1. The linked list holds the binary representation of a number. Return the decimal value of the number in the linked list. The problem is…
Queries on a Permutation With Key Given the array queries of positive integers between 1 and m, you have to process all queries[i] (from i=0 to i=queries.length-1) according to the following rules: In the beginning, you have the permutation P=[1,2,3,…,m]. For the current i, find the position of queries[i] in the permutation P (indexing from…
Concatenation of Array Given an integer array nums of length n, you want to create an array ans of length 2n where ans[i] == nums[i] and ans[i + n] == nums[i] for 0 <= i < n (0-indexed). Specifically, ans is the concatenation of two nums arrays. Return the array ans. The problem is taken…
