What does the following Javascript function do? function mysteryFunction(arg) { for (let key in arg) { if (typeof(arg[key]) "number") { === arg[key] * 2 arg[key]; } } return arg; } а. Takes an object as an argument and adds a new key that is twice the value of the maximum of the old keys. O b. Takes an object as an argument, loops through the entries of the object, and if the value of the entry is numeric, doubles it and returns the modified object. Creates an array of type "number" and sets each array element to be twice the value of the previous element.

What's Hiding Amongst the Crowd? Language - Java Script A word is on the loose and now has tried to hide amongst a crowd of tall letters! Help write a function to detect what the word is, knowing the following rules: The wanted word is in lowercase. The crowd of letters is all in uppercase. Note that the word will be spread out amongst the random letters, but their letters remain in the same order. ● Examples detectWord("UcUNFYGaFYFYGtNUH") → "cat" detectWord("bEEFGBuFBRrHgUHINFYaYr") → "burglar" detectWord("YFem HUFBbezFBYZF BYLleGBYEFGBMENTment") → "embezzlement"
Given what is supposed to be typed and what is actually typed, write a function that returns the broken key(s). The function looks like: findBrokenKeys (correct phrase, what you actually typed) Examples findBrokenKeys ("happy birthday", "hawwy birthday") ["p"] findBrokenKeys ("starry night", "starrq light") → ["y", "n"] findBrokenKeys ("beethoven", "affthoif5") ["b", "e", "v", "n"] Notes - • Broken keys should be ordered by when they first appear in the sentence. Only one broken key per letter should be listed. • Letters will all be in lower case. ●
Classes, Objects, Pointers and Dynamic Memory Program Description: This assignment you will need to create your own string class. For the name of the class, use your initials from your name. The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer. When you first create an MYString object you should…

Course: Data Structurre and algorithms Language: Java Make a Program in java. Read the properly its easy but explained in theory. You have to solve ( make program ) the question by properly as you can error and ommisions will be accepted please. Kindly make it unque dont copy paste. <You have to solve this question as you can kindly dont excusses> Implement a global function“CompareNumbers”which is passed twoSlinkedListobjects as parametersnamed list1, and list2. The function will compare both the numbers corresponding to the lists and will return 0 if both the numbers are equal, return 1 if number corresponding to list1 is greater and will return 2 if number corresponding to list2 is greater. For this task you have to choose an appropriate data structure that will help you do this task in the most efficient manner with regard to time and space complexity.You are allowed to reverse the linked lists for this task. intCompareNumbers(SlinkedList list1, SlinkedList list2)
