1389. Create Target Array in the Given Order

https://leetcode.com/problems/create-target-array-in-the-given-order

Description

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
