Compares two default allocators. Since default allocators are stateless, two default allocators are always equal.

1) Returns true.
2) Returns false.

The `!=` operator is synthesized from `operator==`. | (since C++20)

### Parameters

lhs, rhs | - | default allocators to compare

### Return value

1) true
2) false
