transformed-array


You are given an integer array nums that represents a circular array. Your task is to create a new array result of the same size, following these rules:


For each index i (where 0 <= i < nums.length), perform the following independent actions:


  • If nums[i] > 0: Start at index i and move nums[i] steps to the right in the circular array. Set result[i] to the value of the index where you land.

  • If nums[i] < 0: Start at index i and move abs(nums[i]) steps to the left in the circular array. Set result[i] to the value of the index where you land.

  • If nums[i] == 0: Set result[i] to nums[i].



Return the new array result.



Note: Since nums is circular, moving past the last element wraps around to the beginning, and moving before the first element wraps back to the end.



 


Example 1:




Input: nums = [3,-2,1,1]



Output: [1,1,1,3]



Explanation:




  • For nums[0] that is equal to 3, If we move 3 steps to right, we reach nums[3]. So result[0] should be 1.

  • For nums[1] that is equal to -2, If we move 2 steps to left, we reach nums[3]. So result[1] should be 1.

  • For nums[2] that is equal to 1, If we move 1 step to right, we reach nums[3]. So result[2] should be 1.

  • For nums[3] that is equal to 1, If we move 1 step to right, we reach nums[0]. So result[3] should be 3.




Example 2:




Input: nums = [-1,4,-1]



Output: [-1,-1,4]



Explanation:




  • For nums[0] that is equal to -1, If we move 1 step to left, we reach nums[2]. So result[0] should be -1.

  • For nums[1] that is equal to 4, If we move 4 steps to right, we reach nums[2]. So result[1] should be -1.

  • For nums[2] that is equal to -1, If we move 1 step to left, we reach nums[1]. So result[2] should be 4.




 


Constraints:




  • 1 <= nums.length <= 100

  • -100 <= nums[i] <= 100
