A sloppy Python programmer wrote the following code, which is supposed to check whether asystem of linear equations is solvable, and calculate and print the solution if it is.As you will notice, the code contains syntax and/or logical errors. Select all lines that exhibit errors.import numpy as np:# solve the linear system A x = b for xA = np.array([[1-1] [2 2 0] [3 -1 1]])☐ b = np.linspace (-1, 1, 3)O if A.trace() != 0:x = np. linalg.solve(A, b)print (f"x = {x}")

Let's provide a more detailed explanation of each corrected line:import numpy as np: This line…

8. Write the python code that takes in an array and prints out all pairs of integers from the array whose sum is a prime number. For instance, if A = [2, 9, 1, 8], the outcome would be (2, 1) , (2,9) and (9, 8).

A maze is a two dimensional array of chars. Walls are represented as '#'s and ' ' are empty squares. The maze entrance is always in the first row, second column (and will always be an empty square). There will be zero or more exits along the outside perimeter. To be considered an exit, it must be reachable from the entrance. The entrance is not an exit.Here are some example mazes:mazeA7 9# # ###### # # ## # # #### # ## ##### ## ########## RequirementsWrite a MazeSolver class in Java. This program needs to prompt the user for a maze filename and then explore the maze. Display how many exits were found and the positions (not indices) of the valid exits. Your program can display the valid exits found in any order. See the examples below for exact output requirements. Also, record…
The solution must be recursive. inputAndPrintReverse:Inputs integers from the user until the user enters 0, then prints the integers in reverse order. For this method, you may NOT use an array or any type of array structure, in other words, you may not use any structure to store the user input.
Java - Given the following method header, give the code for the function using a binary search of an array. Don’t worry about the precondition (assume this is already true). public static boolean has10 (int[ ] data, int start, int end) // Precondition: The elements data[start]...data[end] are sorted from smallest to largest. This // array segment might be empty (indicated by end being less than start). // Postcondition: A true return value indicates that the number 10 appears in the array // data[start]...data[end]. A false return value indicates that 10 doesn’t appear.
Given an array of size N-1 such that it only contains distinct integers in the range of 1 to N. Find the missing element. Example 1: Input:N = 5A[] = {1,2,3,5}Output: 4 Write the code for this problem in C++ and Python3
Write the following program in JAVA A magic square is an n x n matrix which, if filled with numbers, the sum of the elements in each row, each column, and the two diagonal is the same value. Write a program that asks the user to for the size of an n x n matrix (square), stores the values in a two dimensional array and prints whether the values entered form a magic square.The program must use methods, loops and two dimensional arrays for this assignment. The main method should show the flow of the program as discussed in class.Sample Run 1:Enter the size of the square3Enter the numbers in each row separated by a space11 1 11 1 11 1|1 1 1 | |1 1 1 | |1 1 1 |Magic SquareSample Run 2:Enter the size of the square4Enter the numbers in each row separated by a space111 1 121 1 111 1 111 1|1 1 1 1 | |1 2 1 1 | |1 1 1 1 | |1 1 1 1 |Not a Magic SquarePlease note: The name
In C language! Write a main.c program to find the greatest common divisor (GCD) of an array of 10 integers. These 10 integers are {64, 16, 36, 24, 8, 32, 72, 144, 48, 72}. Run your codes. The greatest common divisor of two integers is the largest number that can divide these two integers. The Euclid’s algorithm for finding the GCD of two integers is described as follows:  find the smaller of the two integers  use the smaller value as the divisor and the larger number as the dividend  divide the dividend by the divisor  obtain the quotient and the remainder  if the remainder is not zero, the previous divisor becomes the dividend and the remainder becomes the divisor  repeat this division process until the remainder becomes zero  when the remainder is zero, the last divisor in the last step is the GCD.
In PYTHON (Sum the major diagonal in a matrix) Write a function that sums all the numbers of the major diagonal in an n × n matrix of integers using the following header:def sumMajorDiagonal (m):The major diagonal is the diagonal that runs from the top left corner to the bottom right corner in the square matrix. Write a test program that reads a 4 × 4 matrix and display the sum of all its elements on the major diagonal.Program Sample Run (With Input Shown in Bold)Enter a 4-by-4 matrix row 0: 1 2 3 4Enter a 4-by-4 matrix row 1: 5 6.5 7 8Enter a 4-by-4 matrix row 2: 9 10 11 12Enter a 4-by-4 matrix row 3: 13 14 15 16Sum of the elements in the major diagonal is 34.5
