Accepting child class objects in base class type array

[czgdp1807]

Description of the problem

Currently, arrays in arrays.py look for exact type match of elements before adding an element of the array using type. This approach is cryptic. Instead, _check_type should be used. See,

pydatastructs/pydatastructs/linear_data_structures/arrays.py

Line 78 in aebae4c

if dtype != type(args[0][i]):

Well, the following suggests that type understands the class hierarchy but still it shouldn't be used,

>>> from pydatastructs import DynamicOneDimensionalArray as DODA
>>> from pydatastructs.linear_data_structures.arrays import DynamicArray as DA
>>> type(DA) == type(DODA)
True
