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:

$-17$

Note: The function does not just return the largest value, which for $-17-8-2$ would be $-2.$ Though not necessary, you may use the built$-$in absolute value function to determine the max magnitude, but you must still output the input number $($Ex: Output $-17,$ not $17).$

Note from Prof J: $$Built$-$in Python function abs$$can be invoked with an integer paramter; it will return the absolute value of that integer.

Your program must define and call the following function:

def max$\_$magnitude$($user$\_$val$1,$ user$\_$val$2,$ user$\_$val$3)$
