Exercise : pow

Write a method named pow that accepts a base and an exponent as parameters and returns the base raised to the given power. For example, the call pow(3, 4) returns 3 * 3 * 3 * 3 or 81. Do not use Math.pow in your solution; use a cumulative algorithm instead. Assume that the base and exponent are non-negative. See ch4 lecture slides on cumulative sums for a hint.

• For added challenge, try turning your solution into a second version pow2 that works with real number bases and negative exponents, as in book Exercise 4.11.
