**Reverse Iterator**: Similar to input iterators but can be used for multiple passes over the elements in a container. They cannot move forward.
|
||||
|
||||
Example:
|
||||
|
||||
```cpp
|
||||
std::list<int> nums = {1, 2, 3, 4};
|
||||
std::list<int>::reverse_iterator itr = nums.rbegin();
|
||||
while (itr != nums.rend()) {
|
||||
std::cout << *itr << " ";
|
||||
++itr;
|
||||
}
|
||||
```
|
||||
|
||||
- **Bidirectional Iterator**: These iterators offer the ability to move both forward and backward in a container. List and set containers have bi-directional iterators.

|

Example:
