3.3 Let's say we have an array of length X+1. How would we define array[x]? or What is array[x] defined for?

Suppose that points is an array of 10 components of type double, and points = {9.9, 9.6, 8.5, 8.5, 7.8, 7.7, 6.5, 5.8, 5.8, 4.6}The following is supposed to ensure that the elements of points are in nonincreasing order. What is the output of this code? There are errors in the code. Find and correct the errors. for (int i = 0; i < 10; i++)if (points[i + 1] >= points[i])cout << "points[" << i << "] and points[" << (i + 1)<< "] are out of order." << endl;

Lab 23.1: Basic Array Skills Let's work on some basic skills by creating a program that contains a few experiments with arrays. If you are asked to print out a value, be sure to print a label that indicates what the value represents, unless otherwise indicated. For example, if you are asked to print a variable z, the output might look like this: z: 8.0 Create a new Eclipse project. Download the source code file Array_Lab1a.java. Import the source code file into your project. Add your name and section number in the comment block near the top, and then add Java statements that perform each of the following tasks: a) Create an array x of 20 random double values, each between 1.0 and 100.0 (i.e., declare/create the array, then populate it with 20 random doubles). b) Output the number of items in the array by printing the expression x.length. c) Output the first array item, x[0]. d) Output the last array item. Be careful to choose the right index. e) Print the expression x [x.length 1]. Why…

java          (1) Implement the function by allocating a new n X n 2D array. Then write the rotation to it by writing the rows of the original matrix to the columns in the solution matrix such that they fit the solution require[1]ment. Then copy the new matrix exactly the same to the original matrix so that you know for sure you have updated the original matrix to look modified. (2) Implement the function by not allocating a new n X n 2D array. Hint : Perform the rotation in a layer by layer fashion - meaning - different layers can be processed independently. Also within a layer, you can exchange groups of four elements at a time to perform the rotation. Example : Send 1 to 4’s location, 4 to 16’s location, 16 to 13’s location and 13 to 1’s location. Ungraded but Important : As a comment in your code for Problem 2, write your observation on the different solutioning methods utilized. should speak in terms of Time and Space Complexity. Which solution does what in terms of time and…

Below is how the arrays are represented ARRAY1[] = [1, 5, 6, 6, 9, 9, 9, 11, 11, 21] Here length of ARRAY1 is m. ARRAY2[] = [6, 6, 9, 11, 21, 21, 21] Here length of ARRAY2 is n. Array to be returned would be: ARRAY[] = [6, 9, 11, 21] ATTN : Further, please be reminded that you cannot use library functions to either sort and or perform the de-duplication operation. solve the problem in two ways In a separate implementation, code up a solution in such a way that your solution solves the problem with O(nlog(m)) time complexity 2 or O(mlog(n)) time complexity. Here log means to the base of 2. I’m sure you already know that the hint is to use Binary Search. In the form of sentences, as a comment in your code (at the bottom of your Solution2), you are required to suggest how can Solution2 be improved by leveraging the fact that both the arrays are already sorted. Suggest a solution so that your suggested solution can run linearly with O(m + n) time complexity. Your suggestion should be no…
