Given two arrays of integers `nums` and `index`. Your task is to create target array under the following rules:

- Initially target array is empty.
- From left to right read nums[i] and index[i], insert at index `index[i]` the value `nums[i]` in target array.
- Repeat the previous step until there are no elements to read in `nums` and `index.`

Return the target array.

It is guaranteed that the insertion operations will be valid.

Example 1:

    Input: nums = [0,1,2,3,4], index = [0,1,2,2,1]
    Output: [0,4,1,3,2]
    Explanation:
    nums       index     target
    0            0        [0]
    1            1        [0,1]
    2            2        [0,1,2]
    3            2        [0,1,3,2]
    4            1        [0,4,1,3,2]

Example 2:

    Input: nums = [1,2,3,4,0], index = [0,1,2,3,0]
    Output: [0,1,2,3,4]
    Explanation:
    nums       index     target
    1            0        [1]
    2            1        [1,2]
    3            2        [1,2,3]
    4            3        [1,2,3,4]
    0            0        [0,1,2,3,4]

Example 3:

    Input: nums = [1], index = [0]
    Output: [1]

Constraints:

- `1 <= nums.length, index.length <= 100`
- `nums.length == index.length`
- `0 <= nums[i] <= 100`
- `0 <= index[i] <= i`
