Question
Use the arrays below, X and w
Calculate the dot product of X and w. Put the outcome inside the variable dotted_array.
X = np.ones((5, 5))
w = np.arange(5).reshape(1, -1)
print(f"X shape: {X.shape}")
print(f"w shape: {w.shape}")
# TODO 1
dotted_array =
print(f"dotted_array output: \n {dotted_array}")
print(f"dotted_array shape: {dotted_array.shape}")
todo_check([
(dotted_array.shape == (5,1),'dotted_array does not have the correct shape of (5,1)'),
(np.all(dotted_array == np.array([10,10,10,10,10])),'dotted_array does not have the correct values')
])

The program should have an array of five integers named winningDigits, with a randomly generated number in the range of 0 through 9 for each element in the array. The program should ask the user to enter five digits and should store them in a second integer array named player. The program must compare the corresponding elements in the two arrays and count how many digits match. For example, the following shows the winningDigits array and the Player array with sample numbers stored in each. There are two matching digits, elements 2 and 4. The grand prize winner is determined by all 5 matching digits. The program should use functions for the following processes (3):Random number generation for lotteryPrompt for user data entryMatch Processing and Winner Determinationarrow_forwardArray_1 25 70 80 99 30 15 86 77 66 89 55 24 31 20 30 40 15 91 65 63 17 30 29 45 18 49 71 46 89 88 87 86 Fig2 Use array_1 in Fig2 to answer the following question: What is the value in position [2][3]? __________.

- Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forwardShift Left k Cells Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]arrow_forwarduse the array built to shuffle and deal two poker hands. Change the corresponding values for all Jacks through Aces to 11, 12, 13, 14 respectively. Shuffle the deck, then deal two hands. Comment your code and submit the Python code. i wrote a code for it but its not displaying properly, can someone tell me why? (black and white is the array given/ the picture of the python app is what i wrote) its only displaying the array given and not the bottom code i put, why?arrow_forward
