Write a method integerPower$($ base, exponent$)$ that returns the value of

base ${?}^{\text{e}\text{x}\text{p}\text{o}\text{n}\text{e}\text{n}\text{t}}$

For example, integerPower $(3,4)$ calculates $34($or $3*3*3*3).$ Assume that exponent is a positive, nonzero integer and that base is an integer. Method integerPower should use a for or while loop to control the calculation. Do not use any math$-$library methods. Incorporate this method into an application that reads integer values for base and exponent and performs the calculation with the integerPower method.

Write a method minimum$3$ that returns the smallest of three floating$-$point numbers. Use the Math.min method to implement minimum$3.$ Incorporate the method into an application that reads three values from the user, determines the smallest value and displays the result.
