CODEKATA BITWISE

Given a number N and an array of N elements, find the Bitwise XOR of the array elements.
Input Size : N <= 100000
Sample Testcase :
INPUT
2
2 4
OUTPUT
6

 

// ONE TESTCASE PASSED
const readline = require("readline");

const inp = readline.createInterface({
  input: process.stdin
});

const userInput = [];

inp.on("line", (data=> {
  userInput.push(data);
});

inp.on("close", () => {
  var N = Number(userInput[0]);
  var str =String(userInput[1])
  var arr = str.split(' ').map((val)=>Number(val))
  
  var first = arr[0]
  
  for(i=1;i<N;i++)
  { first =first^arr[i]}
  console.log(first)
});

  DATA BASE Backend deals with Server and Data Base CLOUD COMPUTING Cloud – Cloud Computing -- Rented Computer Service Ram, Processor, OS, Storage WHY WE PREFER CLOUD COMPUTING 1. Capital Investment (at initial stage renting is better than purchasing) 2. Maintenance Problem (Power Backup, Hard Disk, Upgrade) 3. Easily Swappable (Scale Up & Scale Down) (festival time ecommerce need extra storage and facilities after that it may need less, College websites during exam time (E.g)   Anna university website ,recent time – income tax website – pan card & aadhar card linking) 4.   Don’t need any separate place to keep those Systems. TOP COMPANIES AWS – Amazon Web Service - Netflix GCP – Google Cloud Platform Azure - Microsoft Azure WHY LINUX PREFERRED THAN OTHER OS Linux, Windows, Mac 1.

  DOM – DOCUMENT OBJECT MODE   HTML DOC –Browser – Browser Engine(html parser) – DOM   Tree structure takes less time for searching that’s why we prefer tree structure in DOM. Why we prefer object model? Object model means OOPS concept based it have features like data abstraction, encapsulation…. Window   -- Window is the default thing available in the Browser’s JavaScript Engine. Document -- Document is property of Window Screen – Physical dimension of   the browser   Draw some sampl tree We can create html with the help of tag and make it dynamic(to do some action) by adding   javascript   using script tag then why specifically we need this dom à Will understand in future classes that we can’t do something directly with the tag.   DOM MANIPULATION   var element =document.createElement(‘tag’) Element.setAttribute(“attribute”,”name”) If we have morethan one same attribute for the element we can’t use s...
