Dowell Permutation Function

To use the Dowell Permutation Function, you need to follow these steps:

Find Permutation:
- Request: This request is a POST request that generates permutations based on the given parameters. It sends a JSON payload in the request body with the following fields:
  - inserted_id: The ID of the previous permutation (null for the first permutation).
  - nextVariable: The next variable to be included in the permutation.
  - n: The total number of elements available for permutation.
  - r: The number of elements to be selected in each permutation.
  - command: The command to find a permutation.
  \n
- Response: The response returns the generated permutation in JSON format. The response body contains the following information:
  - eventId: An event ID associated with the permutation.
  - n: The total number of elements available for permutation.
  - r: The number of elements selected in each permutation.
  - numberOfPermutations: The total number of possible permutations.
  - permutationVariables: An array of arrays, where each inner array represents a permutation with the selected variables.
  - inserted_id: The ID of the inserted permutation.
  \n
\n
Save Permutation:
- Request: This request is a POST request that saves a selected permutation. It sends a JSON payload in the request body with the following fields:
  - inserted_id: The ID of the permutation to be saved.
  - selectedPermutation: An array of variables representing the selected permutation.
  - command: The command to save the permutation.
  \n
- Response: The response confirms the successful saving of the permutation. The response body contains a success message.
\n
Show Permutation:
- Request: This request is a POST request that retrieves a specific permutation based on its ID. It sends a JSON payload in the request body with the following fields:
  - inserted_id: The ID of the permutation to be retrieved.
  - command: The command to show the permutation.
  \n
- Response: The response returns the requested permutation in JSON format. The response body contains the following information:
  - eventId: An event ID associated with the permutation.
  - n: The total number of elements available for permutation.
  - r: The number of elements selected in each permutation.
  - permutationVariables: An array representing the selected permutation.
  - inserted_id: The ID of the permutation.
