Method pow

src/main/java/com/thealgorithms/maths/Pow.java:26–35

Computes the value of the base raised to the power of the exponent. The method calculates a b by iteratively multiplying the base a with itself b times. If the exponent b is negative, an IllegalArgumentException is thrown. @param a

(int a, int b)

     * @throws IllegalArgumentException if {@code b} is negative.
