Write a function power(base, exponent) that returns the value base^exponent, i.e. base * base * base * ... * base, where there are exponent many terms of the product. For example, powerLoop(2,5) = 2^5 = 32 because 2*2*2*2*2 = 32. Do not use the operator **. Instead, use an accumulator and a for loop that runs n times.
