void sort_vectors(const short *v[], int type);

-1-terminated vector of shorts: -1 denotes out of bounds?
so the vector is of length n+1, when you have n elements,
where the n+1th element is -1
no negative elements

short: 16-bits
long: 32-bits

sort the values by:
-smallest to largest (vice versa)


pointers are being switched so you don't have to copy the data;
only copy the pointer to the data


pointers 5 4 1 3 7 5 8
values:  1 3 5 7 9 0 3

pointers : 1 3 4 5 

switch the values a and b:
temp = a
a = b
b = temp

temp = *a
*a = *b
*b = temp


sum: sum of all elements in vector (except for terminator)

if type == 0{
	goto sort_the_vectors_by_sum elements/vector
}
for each vector sum all elements (except for terminator)
sort the vectors by their sum
