/*
* 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.
*
* 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]
