$5\mathrm{.}15$ LAB: Max magnitude

Write a function max magnitude$()$ with three integer parameters that returns the largest magnitude value. Use the function in the main program that takes three integer inputs and outputs the largest magnitude value.

Ex$.$ If the inputs are:

$579$

function max.magnitude$()$ returns and the main program outputs:

$9$

Ex$.$ If the inputs are:

$-17$

$-8$

$-2$

function max$\_$magnitude$()$ returns and the main program outputs:
