You are given an array of integers `nums`. You are also given an integer `original` which is the first number that needs to be searched for in `nums`.

You then do the following steps:

1. If `original` is found in `nums`, multiply it by two (i.e., set `original = 2 * original`).
2. Otherwise, stop the process.
3. Repeat this process with the new number as long as you keep finding the number.

Return the final value of `original`.

Example 1:

    Input: nums = [5,3,6,1,12], original = 3
    Output: 24
    Explanation:
    - 3 is found in nums. 3 is multiplied by 2 to obtain 6.
    - 6 is found in nums. 6 is multiplied by 2 to obtain 12.
    - 12 is found in nums. 12 is multiplied by 2 to obtain 24.
    - 24 is not found in nums. Thus, 24 is returned.

Example 2:

    Input: nums = [2,7,9], original = 4
    Output: 4
    Explanation:
    - 4 is not found in nums. Thus, 4 is returned.

Constraints:

- `1 <= nums.length <= 1000`
- `1 <= nums[i], original <= 1000`
