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.

import numpy as np
def encoding(a):
    a = np.array(a)
    i = 0
    b = []
    c = []
    for j in range(len(a)):
        if a[j] == a[i]:
            c.append(a[i])
        else:
            b.append(len(c))
            c = []
            i = j
    b.append(len(c))
    return np.array([a[:len(a)-1], b])
