+
+The **`.swap()`** [method] (https://www.codecademy.com/resources/docs/cpp/methods) exchanges the contents of one deque with another deque of the same type. After the swap, each deque contains the elements that were originally stored in the other. 
+
+## Syntax
+
+```pseudo
+deque1.swap(deque2);
+```
+
+- `deque1`: The first deque that is going to take the content of deque2.
+- `deque2`: The second deque whose contents are exchanged with deque1.
+
+## Example
+
+The following code demonstrates how to swap two integer variables using `.swap()`:
+
+```cpp
+#include <iostream>
+#include <algorithm>
+using namespace std;
+
+int main() {
+  // Create two deques of integers
+  std::deque<int> deque1 = {1, 2, 3};
+  std::deque<int> deque2 = {10, 20, 30, 40};
+
+  // Display elements before swapping
+  std::cout << "Before swap:" << std::endl;
+  std::cout << "Deque 1: ";
+  for (int num : deque1) std::cout << num << " ";
+  std::cout << std::endl;
+
+  std::cout << "Deque 2: ";
+  for (int num : deque2) std::cout << num << " ";
+  std::cout << std::endl;
+
+  // Swap contents
+  deque1.swap(deque2);
+
+  // Display elements after swapping
+  std::cout << "\nAfter swap:" << std::endl;
+  std::cout << "Deque 1: ";
+  for (int num : deque1) std::cout << num << " ";
+  std::cout << std::endl;
+
+  std::cout << "Deque 2: ";
+  for (int num : deque2) std::cout << num << " ";
+  std::cout << std::endl;
+
+  return 0;
+}
+```
+The output of this code is:
+
+```shell
+Before swap:
+Deque 1: 1 2 3 
+Deque 2: 10 20 30 40 
+
+After swap:
+Deque 1: 10 20 30 40 
+Deque 2: 1 2 3
+```
+
+
+## Codebyte Example 
+
+The following codebyte shows a quick example of using the .swap() method with two deques of strings:
+
+We can currently support:
+
+```codebyte/cpp
+#include <iostream>
+#include <deque>
+#include <string>
+
+int main() {
+  std::deque<std::string> dequeA = {"apple", "banana"};
+  std::deque<std::string> dequeB = {"cherry", "date"};
+
+  dequeA.swap(dequeB);
+
+  std::cout << "Deque A:";
+  for (const auto& value : dequeA) std::cout << ' ' << value;
+
+  std::cout << "\nDeque B:";
+  for (const auto& value : dequeB) std::cout << ' ' << value;
+}
+
+```
