So when the number of test cases is enough, any code that initializes the set with clear() can be hacked with a case that inserts a lot of distinct elements, and then spams the smallest case possible. If you're the coder and want to avoid this, then you need to initialize the set...
which are both semantically equivalent to your code (passing {} as the argument of a function call to initialize std::unordered_map<int,int>). That is, in case of a C++11-conforming library, the error is expected, as the selected (default) constructor is explicit, therefore the code is...
All constructors also initialize several stored values. For the copy constructor, the values are obtained from Right. Otherwise:the minimum number of buckets is the argument Bucket_count, if present; otherwise it's a default value described here as the implementation-defined value N0....

If not, it creates such an element X and initializes it with value. The function then determines the iterator where that designates X. If an insertion occurred, the function returns std::pair(where, true). Otherwise, it returns std::pair(where, false)....
// If bucket is empty, initialize it first if (!is_initialized(bucket)) init_bucket(bucket);also, if the bucket is empty, and we are going to initalize it, the key is clearly not in the list. yet the init_bucket() code adds a dummy iterator to the bucket so that the next giant...
