1389 - Create Target Array in the Given Order\.

Easy

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 numsi and indexi, 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
