Compares the contents of two arrays.
1-2) Checks if the contents of lhs and rhs are equal, that is, whether each element in lhs compares equal with the element in rhs at the same position.
3-6) Compares the contents of lhs and rhs lexicographically. The comparison is performed by a function equivalent to std::lexicographical_compare.

Parameters

lhs, rhs - containers whose contents to compare
-
T must meet the requirements of EqualityComparable in order to use overloads (1-2).
-
T must meet the requirements of LessThanComparable in order to use overloads (3-6). The ordering relation must establish total order.

Return value

1) true if the contents of the containers are equal, false otherwise
2) true if the contents of the containers are not equal, false otherwise
3) true if the contents of the lhs are lexicographically less than the contents of rhs, false otherwise
4) true if the contents of the lhs are lexicographically less than or equal the contents of rhs, false otherwise
5) true if the contents of the lhs are lexicographically greater than the contents of rhs, false otherwise
6) true if the contents of the lhs are lexicographically greater than or equal the contents of rhs, false otherwise

Complexity

Linear in the size of the container
