Internally, the elements in the unordered_set are not sorted in any particular order, but organized into buckets depending on their hash values to allow for fast access to individual elements directly by their values (with a constant average time complexity on average). unordered_set containers ar...
find finds element with specific key (public member function) contains (C++20) checks if the container contains element with specific key (public member function) equal_range returns range of elements matching a specific key (public member function) ...

Since an unordered_map has elements in the form of key-value pairs, we use the operator ([]) to extract the corresponding value of a key present in the map. While in an unordered_set, there is no such operator. The searching for an element is done using afind function. ...

Parameters n Bucket number. This shall be lower thanbucket_count. It is an optional parameter that changes the behavior of this member function: if set, the iterator retrieved points to the first element of a bucket, otherwise it points to the first element of the container. ...
