## Overview
This Pre-Built consists of a JST document that finds the first available consecutive pair of numbers from a given starting integer, a given ending integer, and a given array of already allocated integers (`allocated`).

For instance, a range is defined by start and end values: ex: 0 through 255. These values are assumed for the following examples.

Example 1: `allocated: [12,200,199,0,2,4,100,101,150]`. The output from this JST is an object containing the next available consecutive pair of numbers availible in the range. `{ "assigned": [5,6] }`.

Example 2: `allocated: [187,19,0,1,2,18,10,140]` The output for this JST will be `{ "assigned": [3,4] }`.

In case the range is all allocated, the output object will be:  `{ "assigned": false }`

Example use cases when this JST can be used: an array of ports, an array of IP addresses (can only handle 1 quadrant: 0-255), etc.

## Installation Prerequisites

Users must satisfy the following pre-requisites:

<!-- Include any other required apps or adapters in this list -->
<!-- Ex.: EC2 Adapter -->
* Itential Automation Platform
  * `^2022.1.x`


## Features

The main benefits and features of the Pre-Built are outlined below.
 * Finds the first available consecutive pair of numbers within an array. 
<!-- Unordered list highlighting the most exciting features of the artifact -->
<!-- EXAMPLE -->
<!-- * Automatically checks for device type -->
<!-- * Displays dry-run to user (asking for confirmation) prior to pushing config to the device -->
<!-- * Verifies downloaded file integrity (using md5), will try to download again if failed -->


## Future Enhancements
 * Increasing an algorithm's efficiency by converting logic onto a recursive call.
<!-- OPTIONAL - Mention if the artifact will be enhanced with additional features on the road map -->
<!-- Ex.: This artifact would support Cisco XR and F5 devices -->

## How to Install

To install the artifact:

* Verify you are running a supported version of the Itential Automation Platform (IAP) as listed above in the [Requirements](#requirements) section in order to install the Pre-Built.
* The Pre-Built can be installed from within App-Admin_Essential. Simply search for the name of your desired artifact and click the install button.

<!-- OPTIONAL - Explain if external components are required outside of IAP -->
<!-- Ex.: The Ansible roles required for this artifact can be found in the repository located at https://gitlab.com/itentialopensource/pre-built-automations/hello-world -->

## How to Run

In order to run this JST, add the appropriate JST task onto the workflow, then search for "allocateNewPair" and
assign values to all incoming variables:

    startRange: INT
    endRange: INT
    allocated: ARRAY of INT
<!-- Explain the main entrypoint(s) for this artifact: Automation Catalog item, Workflow, Postman, etc. -->
