The product difference between two pairs (a, b) and (c, d) is defined as (a * b) – (c * d). Given an integer array nums, choose four distinct indices w, x, y, and z such that the product difference between pairs (nums[w], nums[x]) and (nums[y], nums[z]) is maximized. Return the maximum such product difference….
A square triple (a,b,c) is a triple where a, b, and c are integers and a2 + b2 = c2. Given an integer n, return the number of square triples such that 1 <= a, b, c <= n. Example 1: Input: n = 5Output: 2Explanation: The square triples are (3,4,5) and (4,3,5). Example 2:…
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. Example 1: Input: nums = [1,2,1]Output: [1,2,1,1,2,1]Explanation:…
Given a string s, return the number of unique palindromes of length three that are a subsequence of s. Note that even if there are multiple ways to obtain the same subsequence, it is still only counted once. A palindrome is a string that reads the same forwards and backwards. A subsequence of a string…
You are given an m x n matrix maze (0-indexed) with empty cells (represented as ‘.’) and walls (represented as ‘+’). You are also given the entrance of the maze, where entrance = [entrancerow, entrancecol] denotes the row and column of the cell you are initially standing at. In one step, you can move one…
You are given coordinates, a string that represents the coordinates of a square of the chessboard. Below is a chessboard for your reference. Flow Diagram: – Solution: –
You are given a string word that consists of digits and lowercase English letters. You will replace every non-digit character with a space. For example, “a123bc34d8ef34″ will become ” 123 34 8 34″. Notice that you are left with some integers that are separated by at least one space: “123”, “34”, “8”, and “34”. Return…
Given an array of positive integers nums, return the maximum possible sum of an ascending subarray in nums. A subarray is defined as a contiguous sequence of numbers in an array. A subarray [numsl, numsl+1, …, numsr-1, numsr] is ascending if for all i where l <= i < r, numsi < numsi+1. Note that…
Given an alphanumeric string s, return the second largest numerical digit that appears in s, or -1 if it does not exist. An alphanumeric string is a string consisting of lowercase English letters and digits. Example 1: Input: s = “dfa12321afd”Output: 2Explanation: The digits that appear in s are [1, 2, 3]. The second largest…
In many cases we can face the error related to SSL certificate as mentioned below :- So, this error in Edge browser can be handled using EdgeOptions class provided by Selenium Web driver. The sample code block is mentioned below:- In the above code block we are accepting the Insecure certificate by passing Boolean value…
