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.
