	# Problem Statement
	> 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  

	# Explanation
	*   Iterate through the input array `nums`.
*   For each element, calculate the destination index based on its value (positive or negative). Handle the circular array nature using the modulo operator.
*   Store the value at the destination index in the corresponding position of the `result` array.

*   **Runtime Complexity:** O(n), where n is the length of the input array `nums`.
*   **Storage Complexity:** O(n), for storing the `result` array.
