	English ```c++ void reserve(size_type n); ``` 37/10000 · 37
384 :1396

	English Equivalent to `a.rehash(ceil(n / a.max_load_factor()))`, or `a.rehash(1)` if `n > 0` and `a.max_load_factor() == std::numeric_limits<float>::infinity()`. 153/10000 · 153
385 :1398

	English Similar to `rehash`, this function can be used to grow or shrink the number of buckets in the container. 104/10000 · 104

	English Invalidates iterators, and changes the order of elements. Pointers and references to elements are not invalidated. 114/10000 · 114

	English Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the container's hash function or comparison function. 140/10000 · 140

	English - It has an `InputIterator` template parameter and a type that does not qualify as an input iterator is deduced for that parameter. - It has an `Allocator` template parameter and a type that does not qualify as an allocator is deduced for that parameter. - It has a `Hash` template parameter and an integral type or a type that qualifies as an allocator is deduced for that parameter. - It has a `Pred` template parameter and a type that qualifies as an allocator is deduced for that parameter. 494/10000 · 494

	English A `size_type` parameter type in a deduction guide refers to the `size_type` member type of the container type deduced by the deduction guide. Its default value coincides with the default value of the constructor selected. 223/10000 · 223

	English ```c++ template<class Key, class Hash, class Pred, class Alloc> bool operator==(const unordered_set<Key, Hash, Pred, Alloc>& x, const unordered_set<Key, Hash, Pred, Alloc>& y); ``` 180/10000 · 180
396 :1435

	English Return `true` if `x.size() == y.size()` and for every element in `x`, there is an element in `y` with the same key, with an equal value (using `operator==` to compare the value types). 184/10000 · 184

401 :1449

	English Return `false` if `x.size() == y.size()` and for every element in `x`, there is an element in `y` with the same key, with an equal value (using `operator==` to compare the value types). 185/10000 · 185
