A two -dimensional array X. For each line of array X, the following transformation must be made. Let the line X be given. It is necessary to build a new array, where all elements with odd indices are required to be replaced by the number A (the default value A = 1). All elements with even indices need to be built into the cube. Then write the elements in the reverse order regarding their positions. At the end, it is required to drain an array X with a converted X and display. Write a function that performs this transformation for each line of the two -dimensional array X. The array X should remain unchanged. Use the Numpy library. Example: x = [100,200,300,400,500]] -> [[100, A, 300, A, 500]] -> [[500 ** 3, A, 300 ** 3, A, 100 ** 3]] -> -> -> Close -> [[100,200,300,400,500,500 ** 3, A, 300 ** 3, A, 100 ** 3]]]

import numpy as np def transform_array(x, a=1): x = np.array(x) for i, el in enumerate(x): x[i] = el ** 3 if i % 2 == 0 else a return x[::-1] def transform_array_all(x, a=1): x = np.array(x) y = np.array([]) for i, el in enumerate(x): if i % 2 == 0: el = el ** 3 else: el = a y = np.append(y, el) return np.append(x, y[::-1]) x = np.array([100,200,300,400,500]) print(transform_array(x)) print(transform_array_all(x))
