operator<(
stack<VALUE, CONTAINER> const& lhs,
stack<VALUE, CONTAINER> const& rhs);Return true if the value of the specified lhs stack is lexicographically less than that of the specified rhs stack, and false otherwise. Given iterators i and j over the respective sequences [lhs.begin() .. lhs.end())] and [rhs.begin() .. rhs.end())], the value of stack lhs is lexicographically less than that of stack rhs if true == *i < *j for the first pair of corresponding iterator positions where *i < *j and *j < *i are not both false. If no such corresponding iterator position exists, the value of lhs is lexicographically less than that of rhs if lhs.size() < rhs.size(). This method requires that operator<, inducing a total order, be defined for value_type.
