operator< function template — Compares lists for less-than
template <typename T, typename A>
bool operator<(const list<T,A>& x, const list<T,A>& y);
The <
operator
determines whether x
is less than
y
using the same algorithm as
lexicographical_compare(x.begin(
)
, x.end( )
, y.begin( )
, y.end( ))
.
