Question
1. Create a size-specific array of ones (10 , 1). Put the result into the bias array variable.
2. From the list [100, 50, 32, 1000], create an array. Put the result in the array from list variable array_from_list
# TODO 1.1
bias_array =
print(f"bias_array output: \n{bias_array}")
print(f"bias_array shape: {bias_array.shape}")
todo_check([
(bias_array.shape == (10,1),'bias_array does not have the shape (10, 1)'),
(np.all(bias_array == 1),'all values in bias_array are not 1')
])
#TODO 1.2
array_from_list =
print(f"array_from_list output: \n{array_from_list}")
print(f"array_from_list shape: {array_from_list.shape}")
todo_check([
(array_from_list.shape == (4,),'array_from_list did not have the shape (4,)'),
(list(array_from_list) == [100,50,32,1000],'array_from_list did not contain the values [100, 50, 32, 1000]')
])

- A left rotation operation on an array of size n shifts each of the array's elements 1 unit to the left. Given an integer, d, rotate the array that many steps left and return the result. Example:d=2arr=[1,2,3,4,5] After 2 rotations, arr'=[3,4,5,1,2]. Function Description: Complete the rotateLeft function in the editor below. rotateLeft has the following parameters: 1. int d: the amount to rotate by 2. int arr[n]: the array to rotate Returns 1. int[n]: the rotated array Input Format: The first line contains two space-separated integers that denote n, the number of integers, and d, the number of left rotations to perform.The second line contains n space-separated integers that describe arr[]. Constraints: 1. 1<=n<=10^5 2. 1<=d<=n 3. 1<=a[i]<=10^6arrow_forwardProgramming language: Processing from Java Question attached as photo Topic: Use of Patial- Full Arraysarrow_forwardint [] arrayInt={3,54,90,22,32}; To print the last element in the arrayInt you will write: a.

- 2DArray method:It will allocate a block of memory which represents a two-dimension arraybased on the input values supplied by the user. Ask the user to enter the number of rows andcolumn for 2D array that the user want to manipulate. The number of rows and columns that theuser enters may or may not define a square matrix (when the number of rows equals the numberof columns). The array will have exactly rows time columns (m * n) elements. It will notcontain any extra or empty cells. Initialize the “matrix” by rows with random number between 1to 100. Pass two arguments by out reference so that you can assign the number of row andcolumns of data to the first and second arguments. This is return 2D array method afterallocating new memory for 2D array and initialize it with random value. Generate randomnumber code in C# as following: Random randnum = new Random( );int number = randnum.Next (1, 101);SwapRow method: it will rotate the data in the matrix in an up/down method such that the…arrow_forwardvoid changeAll(int x[]) { x[0] = x[0] + 5; return; The first element in an array would be increased by 5 The array would be the same because it was passed by value x would be increased by 5 All the elements in the passed array would be incremented by 5arrow_forwardReturn the First Element in an Array JavaScript Create a function that takes an array containing only numbers and return the first element.
