2.3.3 Implementation Parameters
Many of the parameterized data type templates (, e.g., dictionary, priority queue, d array,
and sortseq) take an optional data structure parameter for choosing a particular implementation
(, e.g., d array). We can easily modify the example program from
Section 2.1 to use a dictionary array implemented by a particular data structure, e.g.,
skip lists, instead of the default data structure (cf. Section 18.1).

using namespace leda;

{
d_array
string s;
N(0);
}
while (cin >> s) N[s]++;
