Return true if the specified lhs and rhs objects do not have the same value, and false otherwise. Two stack objects lhs and rhs do not have the same value if they do not have the same number of elements, or some element in the ordered sequence of elements of lhs does not have the same value as the corresponding element in the ordered sequence of elements of rhs. This method requires that the (template parameter) type VALUE be equality-comparable (see {Requirements on VALUE}).
