Could you tell me how to resize the array in order? For example:
If the input is:
>>> np.arange(4)
array([0, 1, 2, 3])
The output will be:
array([0, 0, 1, 1, 2, 2, 3, 3])

In [1]: import numpy as np
In [2]: a = np.arange(4)
In [3]: a
Out[3]: array([0, 1, 2, 3])
In [4]: np.repeat(a, 2)
Out[4]: array([0, 0, 1, 1, 2, 2, 3, 3])
