Double the numbers

the goal of this code is to get quickly off the ground with array method map().

input

• the input will be single line containing an array myArray

output

• the output will be single line containg the newArray

constraints

• strings should be given in quotes

sample input1

[1, 'David', 10, {'points':97}, 25, 'alphabet', true]

sample output1

[2, 'string' 20, 'object', 50, 'string' 'boolean']

function readLine() {

 return inputString[currentLine++];

}

function main() {

 const myArray = JSON.parse(readLine().replace(/'/g, '"'));

/* Please do not modify anything above this line */

 // Write your code here

}

the goal of this code is to quickly get you off the ground with Creating and Consuming Promises.

input

• the first line of input is containing a boolean isHotWaterReady
• the second line of input is containing a boolean isBreakfastReady

output

• the output could be multiple strings with the appropriate response in seperate lines

based on inputs

sampleinput1

true

true

sampleoutput1

Taken Shower

Had Breakfast

Got to Work

function main() {

 const isHotWaterReady = JSON.parse(readLine());

 const isBreakfastReady = JSON.parse(readLine());

/* Please do not modify anything above this line */

 // Write your code here

 const takingShower = () => {

   return new Promise((resolve,reject) => {

     isHotWaterReady ? resolve("Taken Shower") : reject ("Hot Water Not Ready")

   });

 }

 const breakFast = () => {

   return new Promise((resolve,reject) => {

      isBreakfastReady ? resolve("Had Breakfast") : reject ("Breakfast Not Ready")

   });

 }

You have given A and B as two lists with may have repeated element in the respective list. Write a python function Merge_List(A, B) which take list A and B as input and return a merged list. The function will merge the list B with A (means the list A will be expanded) such that the resultant A still contain no duplicates.

the goal of this coding exam is to quickly get off you the ground with the array method every().

input

• the input will be single line containing an array of objects candidatesList

output

• the output should be single line containing an array with names of the selected candidates.

input1

[{'name': 'Blake Hodges', 'points':[76, 98, 88, 84]}

output1

['Blake Hodges]

"use strict";

process.stdin.resume();

process.stdin.setEncoding("utf-8");

let inputString = "";

let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

 inputString += inputStdin;

});

process.stdin.on("end", (_) => {

 inputString = inputString.trim().split("\n").map((str) => str.trim());

 main();

});

function readLine() {

 return inputString[currentLine++];

}

function main() {

 const candidatesList = JSON.parse(readLine().replace(/'/g, '"'));

Bob a builder has come to you to build a program for his business. He needs to determine the square footage of a room in order to buy materials and calculate costs. Bob charges $125 per square metre. The program is going to ask the user to enter the name of a room. It will then ask for the width and length of the room (in meters) to be built. The program will calculate the room area and use this information to generate an approximate cost. Your program will display the room, the total area and the approximate cost to the screen.
