Computer Science Please use PYTHON (if/when necessary) to answer the following. Thank you. The following function calculates x to the nth power, where n is an integer: class Calculator: def pow(self, x, n): if x==0 or x==1 or n==1: return x if x==-1: if n%2 ==0: return 1 else: return -1 if n==0: return 1 val = self.pow(x,n//2) if n%2 ==0: return val*val return val*val*x a) Use unittest to test it. For example: test whether the program gives the correct answer when n is a negative value, 0 or a very large value. Please provide your answer by USING PYTHON. b) When n is negative, this code (as shown above) may return a wrong result of calculation. How can you improve the quality of your code? (Hint: pow(x,n) = 1/pow(x,-n))

Computer Science
Please use PYTHON (if/when necessary) to answer the following. Thank you.
The following function calculates x to the nth power, where n is an integer:
class Calculator:
def pow(self, x, n):
if x==0 or x==1 or n==1:
return x
if x==-1:
if n%2 ==0:
return 1
else:
return -1
if n==0:
return 1
val = self.pow(x,n//2)
if n%2 ==0:
return val*val
return val*val*x
a) Use unittest to test it. For example: test whether the program gives the correct answer when n is a negative value, 0 or a very large value. Please provide your answer by USING PYTHON.
b) When n is negative, this code (as shown above) may return a wrong result of calculation. How can you improve the quality of your code? (Hint: pow(x,n) = 1/pow(x,-n))
