Question. Use Python Code Correctly to solve this problem. And, Use all Examples Please. Rotate Image You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. Example 1: Input: matrix = [[1,2,3],[4,5,6],[7,8,9]] Output: [[7,4,1],[8,5,2],[9,6,3]] Example 2: Input: matrix = [[5,1,9,11],[2,4,8,10],[13,3,6,7],[15,14,12,16]] Output: [[15,13,2,5],[14,3,4,1],[12,6,8,9],[16,7,10,11]]

3D Array: Use python to solve this problem. We already know how to operate 2D arrays. Now we have to use 3D arrays in order to construct LCS with 3 parameters. Multidimensional array means multiple arrays of different dimensions or sizes can be held by a single array. We will learn about 3D arrays with an example. Suppose we want to store midterm and final marks separately of four different courses of three students in a single array. We can easily do it by using a 3D array. Python: for i in range(len(A)): print("Student: ",(i+1)) for j in range(len(A[i])): print("Course: ",(j+1)) print("Marks of Mid and Final: ") for k in range(len(A[i][j])): print(A[i][j][k],end=" ") print() print() OUTPUT: Student: 1 Course: 1 Marks of Mid and Final: 30 25 Course: 2 Marks of Mid and Final: 35 40 Course: 3 Marks of Mid and Final: 41 45 Course: 4 Marks of Mid and Final: 26 26 Student: 2 Course: 1 Marks of Mid and Final: 41 45…
Using Java, Dr. Choi has 5 students who took a midterm and final. 1.First, she wants to store their midterm and final results in two different 1-dimensional arrays and print each of them to a console. 2.She also wants to find average scores of the midterm and final using loops. 3.Second, she wants to store them in one 2-dimensional array and print it to the console. Each row has test scores of the midterm and final. 4.Modify the program above using a 2-dimensional array: Search the highest test score at midterm and lowest test score at final and print them: Pass an array to a method for finding highest score at midterm and lowest test score at final. There are two methods invoked in main () method. One is for finding the highest score and the other one is for finding the lowest score.

Can you ask with the python software language? A 2D matrix can be represented as a list and a column count value in Python. For example, the 3x3 matrix 1 2 3 4 5 6 7 8 9 can be row-wise represented as ([1,2,3,4,5,6,7,8,9], 3), where the number 3 represents the number of columns in the matrix. Similarly, 1 3 5 2 4 6 becomes ([1,3,5,2,4,6], 3). A submatrix can be defined as an (l,r,t,b) tuple, where l and r are left and right column indices, and t and b are top and bottom row indices (all inclusive). Write a function that takes a tuple containing the list representing a matrix, and the column count of the matrix, along with another tuple representing a specific submatrix, and returns the list representation of the submatrix along with its column count as a tuple. For example, given submatrix(([1,2,3,4,5,6,7,8,9,10,11,12], 4), (1,2,0,1)) returns: ([2,3,6,7], 2) def submatrix(matrix, indices):
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.

You are given N 6-sided standard dice. Each die has dimensions 1x1x1. You decide to stack dice. First, you form four vertical stacks of dice (not necessarily with the same height, empty stacks are allowed) on the table, which together make up a pile of dice with a base area of up to 2x2. Among all such structures, the total visible surface area of your structure must be the smallest possible. Then, you calculate the number of dots on the visible faces of all dice in the structure. A face of a die is visible if it doesn't touch the table or another die. Now, you want to compute: among all possible arrangements of N dice, what is the maximum possible total number of visible dots? Hint: Try to compute for N= 1, 2, 3, 4, 5, 6 and find a pattern. Write pseudocode for the poblem.
Write a Java Program to print a 2D matrix in the Spiral format. You can assume the 2D matrix is your own.
You can see in the above display, we first sort each row of the 2D array; we then take the transpose of a two D array, i.e., all the row elements becoming the column elements; we then sort each row of the 2D again. If you read the final array, each row is sorted; each column is also sorted. The smallest element obviously is the 1st element of the two D array and the last element is the largest element of a two D array. Let us now look at the following UML diagram: (Note that additional methods are allowed; proposed methods and instance variable cannot be changed) Main method firstly constructs a 2D array of certain sizes and then construct a TwoD object and drive the task according to the above runtime interactions and displays. TwoD class has only one instance variable which is a two D array of numbers ( int or double). The constructor must do some “deep” copying. A copy constructor. The other three methods are obvious in definition: to sort each row, to rotate the 2D array (i.e.,…
I'm struggling to create 5 histograms for a set of data in Python. Conceptually the code should produce a histogram which gets smoother and closer to a normal curve as the number of values increases in the array. Mine are all plotting on the same graph however and are separated at weird values and I don't know why. They're not curve like at all. For reference, my 5 arrays of values are generated randomly from a normal distribution with a mean of 12, standard deviation of 1, and contain 5, 50, 500, 5000, and 5000000 values respectively.

write a program that can create 2 numpy arrays with the size of rows and columns that can be inputted. The contents of each matrix are random integer numbers from -10 to 10 (including -10 and 10). Then do the multiplication operation on the 2 matrices. Finally, find the highest and lowest values of the matrix multiplication result
