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 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
