Open Pycharm on your PC and create python file named Lab6.py. 1- Write the necessary code to initialize a numpy array (5,3,3) as follows: [[[6 2 6] [6 2 6] [6 2 6]] [[666] [666] [666]] [[666] [333] [666]] [[666] [666] [666]] [[7 6:6] [6 7 6] [667]]] 2- Generate a (7, 7) numpy array that consists of integer random values between 10 and 50 and answer the following: a. What is the minimum value in each column b. What is the mean for each row c. Generate the cumulative product of each column d. Count the number of elements in the array whose values are greater than 30 and smaller than 40 e. Display the elements in the arrays that equals to 20 f. Multiply by 5 the elements whose value is less than 30. g. Display the largest 5 elements in the array 3- Define two numpy 1D arrays X and Y; initialize them to random numbers between 0 and 100 and print the elements in X that do not exist Y.
Write a Java program to do the following: • Create a two-dimensional array named "marks" and size n-by-5 (n X 5). This array represents students' marks in ITCS114 course. Where we have n students registered in this course and each student has 5 assignments. The number of students(n) should be entered by the user. Prompt the user to enter the values of the array. • Make a copy of array "marks" with reverse rows order into another array and name it "rMarks". Where the first row of array "marks" should be copied in the last row of array "rMarks" and so on for all rows. • In the array "marks", add extra one mark in the 3rd assessment for all students who have scored 4.0 or more in this assessment. • Print the values of the "marks" and "rMarks" arrays. For example, if n=4 and "marks" array as follow: 4.5 4.5 1.5 5.0 3.5
We have an array variable ‘var’ int var[4] = {25,20,30,40}; Find the memory address of the first element of in the array: var[0]
Given the Array declaration below, determine the output: int T[8] = {2, 3, 7, 9, -1, 2, 4, 5}; int x = 5; cout << T[x-2] / T[12-2*x]; int y = -3; cout << pow(T[y+4],T[3-y]);
The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number //…
