Using Numpy, write an array coding function (Run-Length Encoding). The function of repetition of elements compresses the function into one element and considers the number of repetitions. The function returns a motorcade of two Numpy veins of the same length. The first contains elements, and the second - how many times they need to be repeated. Example: Encode (np.array ([1, 2, 2, 3, 3, 1, 1, 5, 5, 2, 3, 3, 3])) = (np.array ([1, 2, 3, 1, 1, 1, 1, 1, 5, 2, 3]), np.array ([1, 2, 2, 2, 2, 1, 2]))

def encode(a):
    c = []
    index = 0
    a_len = len(a)
    while index < a_len:
        c.append(a[index])
        b = 1
        while index + 1 < a_len and a[index] == a[index + 1]:
            index += 1
            b += 1
        c.append(b)
        index += 1
    c = np.array(c)
    return c[0::2], c[1::2]
encode(np.array([1,2,2,3,3,1,1,5,5,2,3,3,3,2,2]))
