+Title: 'end()'
+Description: 'Returns an iterator pointing just past the last element of the unordered set, marking the end of the container’s range.'

+
+The **`end()`** method returns an iterator that points to the past-the-end position of an [`unordered_set`](https://www.codecademy.com/resources/docs/cpp/unordered-set). This iterator marks one past the last element and cannot be dereferenced. Because `unordered_set` does not maintain a defined order, iteration proceeds in the container’s internal hash-table order.
+
+## Syntax
+
+```pseudo
+unordered_set_name.end();
+```
+
+**Parameters:**
+
+The `end()` function takes no parameters.
+
+**Return value:**
+
+Returns an `iterator` pointing to the past-the-end position of the `unordered_set`.
+
+Or, to work with a specific bucket:
+
+```pseudo
+unordered_set_name.end(n);
+```
+
+**Parameters:**
+
+- `n` (size_type): The bucket index. Must be less than `bucket_count()`.
+
+**Return value:**
+
+A `local_iterator` pointing to the past-the-end position in bucket `n`. If the bucket is empty, `begin(n) == end(n)`.
+
+## Example
+
+In this example, iteration runs from `begin()` to `end()` to print every element in the `unordered_set`:
+
+```cpp
+#include <iostream>
+#include <unordered_set>
+using namespace std;
+
+int main() {
+  unordered_set<int> unique_numbers = {10, 5, 20, 15};
+
+  for (auto it = unique_numbers.begin(); it != unique_numbers.end(); ++it) {
+    cout << *it << "\n";
+  }
+
+  return 0;
+}
+```
+
+A sample output might be:
+
+```shell
+20
+5
+10
+15
+```
+
+> **Note:** The output order may vary because `unordered_set` does not store elements in any defined sequence.
+
+## Codebyte Example
+
+This example retrieves iterators for a specific bucket in the `unordered_set` and prints all elements stored in that bucket:
+
+```codebyte/cpp
+#include <iostream>
+#include <unordered_set>
+using namespace std;
+
+int main() {
+  unordered_set<string> words = {"cat", "dog", "rabbit", "lion"};
+
+  size_t bucket = 0;
+
+  auto it = words.begin(bucket);
+  auto last = words.end(bucket);
+
+  cout << "Elements in bucket " << bucket << ":\n";
+
+  for (; it != last; ++it) {
+    cout << "  " << *it << "\n";
+  }
+
+  return 0;
+}
+```

-Title: '.querySelectorAll()'
-Description: 'Returns a static (non-live) NodeList of all elements in the document that match the given CSS selectors.'

----
-
-In JavaScript, the **`.querySelectorAll()`** method under the `document` object returns a static (not live) `NodeList` of all elements that match the given group of [selectors](https://www.codecademy.com/resources/docs/css/selectors).
-
-## Syntax
-
-```pseudo
-document.querySelectorAll(selectors);
-```
-
-- `selectors`: Represents a string containing one or more CSS selectors used to match elements in the document. It follows the same rules as CSS selectors and can include:
-  - Type selectors (`div`, `p`, `span`)
-  - Class selectors (`.class-name`)
-  - ID selectors (`#id-name`)
-  - Attribute selectors (`[type="text"]`, `[disabled]`)
-  - Combinations (`div p`, `.container > p`, `ul > li:first-child`)
-
-## Examples
-
-### Example 1
-
-In this example, a `NodeList` of all `<p>` elements in the document is obtained:
-
-```js
-const matches = document.querySelectorAll('p');
-```
-
-### Example 2
-
-The following example returns a list of all `<div>` elements in the document with a class of either `note` or `alert`:
-
-```js
-const matches = document.querySelectorAll('div.note, div.alert');
-```
-
-### Example 3
-
-In this example, a list of `<p>` elements is obtained, whose immediate parent is a `<div>` with the class `highlighted`, and which are inside a container with the ID `test`:
-
-```js
-const container = document.querySelector('#test');
-const matches = container.querySelectorAll('div.highlighted > p');
-```
