vec_sub
Purpose
Returns a vector containing the result of subtracting each element of b from the corresponding element of a.
This function emulates the operation on long long vectors.
Syntax
d=vec_sub(a, b)

Result value
The value of each element of the result is the result of subtracting the value of the corresponding element of b from the value of the corresponding element of a. The arithmetic is modular for integer vectors.
