in c++, use parallel arrays , and srand(time(NULL)) to randomize the two cards dealt at the start Create a Blackjack (21) game. Your version of the game will imagine only a SINGLE suit of cards, so 13 unique cards, {2,3,4,5,6,7,8,9,10,J,Q,K,A}. Upon starting, you will be given two cards from the set, non-repeating. Your program MUST then tell you the odds of receiving a beneficial card (that would put your value at 21 or less), and the odds of receiving a detrimental card (that would put your value over 21). Recall that the J, Q, and K cards are worth ‘10’ points, the A card can be worth either ‘1’ or ‘11’ points, and the other cards are worth their numerical values.

Find the bug and write code to proving you have identified the problem. What is the quick fix Byron's code needs? Byron is trying to define a 4 distinct tuples and access one specific element from each of them, but keeps getting an TypeError in his code for some reason a = (0, 1, 100)b = (-1, True, -0.1)c = (10)d = ("XX", "XY", "XXY")print(a[2], b[-1], c[0], d[2])# Byron's desired output for this code is: 100 -0.1 10 XXY

Write a function secondLargest(array) in JavaScript that returns the second largest value in the array (or undefined if the array doesn't have at least two elements. You must use Array#reduce do the vast majority of the work. (You may do a little pre- and post- processing outside the call to reduce.) The lambda passed to Array#reduce function has parameters in this order: partial, item. For example, secondLargest([1, 3, 2]) should return 2 secondLargest([4]) should return undefined IMPORTANT: Make sure the last line of your submission is module.export = secondLargest;
Write a section of code that creates the pairings for two sets of numbers a = {0 – 5} and b = {9 - 15}. Each number must be paired with all numbers from the other set. This is a cross product, denoted as a x b. That is, for every number in a, it should be listed with every number in b, such as (0, 9), … (0, 15), and so on. Make sure there are no spaces between numbers and the (, ), or comma.
I already asked this question once, but I receivied it in C++ form and not Java. I do my Java programming in Apache NetBeans IDE 12.2. The question is below, but please let it be Java coding: Create a two-dimensional array of type double to contain the three different SD Marks (JD521, PRG521, and IP521) for six different students. A single array of type String must be used to store the student names (Maxwell, Carl, Gerhard, Paul, James, and Cena). Allow a user to enter in a number, ranging from 1 to 6, which will represent the student position in the table MCSD max and present the marks for each respecting module. The program can only stop when the user enter a number greater than 6. Printout the student name including the JD521, PRG521, and IP521 max, the total of marks and the average of all marks. Use a condition statement to decide that the student has passed or not (Pass rate is 70). Thank you.
