In this lab, you are given two arrays of integers nums and index. Your task is to create a target array under the following rules:

  • Initially, the target array is empty.
  • From left to right, read nums[i] and index[i], insert at index index[i] the value nums[i] in the 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.

Examples

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

Challenges

  1. Implement the createTargetArray function and make sure to export it.
  2. Test the implementation with given examples and make sure it passes the constraints.
  3. Experiment with different inputs and analyze the time complexity of the function.
  4. Make sure you're exporting default function
