Compares the contents of the underlying containers of two container adaptors. The comparison is done by applying the corresponding operator to the underlying containers.

Parameters

lhs, rhs - container adaptors whose contents to compare
-T must meet the requirements of EqualityComparable.

Return value

true if the corresponding comparison yields true, false otherwise.

Complexity

Linear in the size of the container.
