What is the negation (complement) of:

`i < A.Length` 

in the context of:

```
Do (i < A.Length )   // is it i == A.Length  or   i > A.Length   ?

```

What is the negation of 

`i <= A.Length` 

in the context of:

```
Do (i <= A.Length )  // is it  i >= A.Length  ?

```

For some reason I can't find a source to confirm.
