Define stubs for the functions get_user_num() and compute_avg(). Each stub should print "FIXME: Finish function_name()" followed by a newline, and should return -1. Each stub must also contain the function's parameters.

Sample output with two calls to get_user_num() and one call to compute_avg():
FIXME: Finish get_user_num()
FIXME: Finish get_user_num()
FIXME: Finish compute_avg()
Avg: -1

code to fill in:

''' Your solution goes here '''

user_num1 = 0
user_num2 = 0
avg_result = 0

user_num1 = get_user_num()
user_num2 = get_user_num()
avg_result = compute_avg(user_num1, user_num2)

print('Avg:', avg_result)
