Write a function with a variable number of arguments that returns the maximum of all of its arguments. The first argument n tells you how many numbers to process. The remaining n signed integers are the numbers to proces. The function will be called with exactly n+1 arguments.
If n is 0 (no numbers to process), return 0. Otherwise, return the maximum of the n numbers.
int max (int n, ... );
Expected solution length: Around 15 lines.
max(2, 1, 2)
