Create an empty unordered map, having a max_load_factor of 1.0, and then create a value_type object for each element in the specified values list, ignoring those having a key that appears earlier in the sequence. Optionally specify a minimum initialNumBuckets, hashFunction, keyEqual, and basicAllocator as for the range constructor.
