57.1% Acceptance
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]
andindex[i]
, insert at indexindex[i]
the valuenums[i]
in the target array. - Repeat the previous step until there are no elements to read in
nums
andindex
.
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
- Implement the
createTargetArray
function and make sure to export it. - Test the implementation with given examples and make sure it passes the constraints.
- Experiment with different inputs and analyze the time complexity of the function.
- Make sure you're exporting default function
