represented using the notation `A == B` and is specified to mean the same as
`(A[ 0 ] == B[ 0 ] && A[ 1 ] == B[ 1 ])`. Inequality testing is defined as
`A != B` and is specified to mean the same as
`(A[ 0 ] != B[ 0 ] || A[ 1 ] != B[ 1 ])`. The functions `assign` and

`(A[ 0 ] != B[ 0 ] || A[ 1 ] != B[ 1 ])`.
The functions `assign`, `back`, `pop_back`, `push_back`, and `size` behave
similarly on arrays as it is defined for c++ std::vector.
When a variable is said to be representable by a signed integer with `x` bits,
it means that the variable is greater than or equal to `-(1 << (x-1))`, and that
