In unordered_map, the elements are not sorted initially based on any particular order with respect to key values or mapped values. Instead, it is but structured into buckets subject to the hash values to permit fast access to distinct items directly by their values of keys. Moreover, the co...
The size of pair<int,int> is 8 bytes. Also notice that we have long long: a data type also 8 bytes long. We can create an unordered_map, and to check our pair we can just do: typedefstd::pair<int,int>pii;std::unordered_map<longlong,int>hashmap;piiobject;hashmap[*((longlong*...

Use a std::map (or std::unordered_map). Unless you know the range of values is small enough to manage in an array (use a std::vector), then use the map. Either way the code that actually does the counting isidentical. The purpose is to create what is called ahistogram-- a graph...
