Implement pow(x, n), which calculates x raised to the power n (i.e., xn).
Question
Implement pow(x, n), which calculates x raised to the power n (i.e., xn).
Solution
Sure, here is a simple Python implementation of the power function:
def pow(x, n):
return x ** n
This function takes two arguments, x and n, and returns x raised to the power n. The ** operator in Python is used for exponentiation.
However, this implementation does not handle cases where n is negative. For that, we need to modify the function as follows:
def pow(x, n):
if n < 0:
return 1 / (x ** abs(n))
else:
return x ** n
In this version of the function, if n is negative, we first calculate x raised to the absolute value of n, then return the reciprocal of that result. If n is not negative, we simply return x raised to the power n as before.
