问题描述:
Write a python function to check whether the given number can be represented as difference of two squares or not.

测试用例:
['assert dif_Square(5) == True', 'assert dif_Square(10) == False', 'assert dif_Square(15) == True']

生成的代码:
def dif_Square(n):
    return n % 4 == 0 or n % 4 == 1

assert dif_Square(5) == True
assert dif_Square(10) == False
assert dif_Square(15) == True
