    2574 - Left and Right Sum Differences.

    Easy

    Given a 0-indexed integer array nums, find a 0-indexed integer array answer where:

    • answer.length == nums.length.
    • answer[i] = |leftSum[i] - rightSum[i]|.

    Where:

    • leftSum[i] is the sum of elements to the left of the index i in the array nums. If there is no such element, leftSum[i] = 0.
    • rightSum[i] is the sum of elements to the right of the index i in the array nums. If there is no such element, rightSum[i] = 0.

    Return the array answer.

    Example 1:

    Input: nums = [10,4,8,3]

    Output: [15,1,11,22]

    Explanation: The array leftSum is [0,10,14,22] and the array rightSum is [15,11,3,0]. The array answer is [|0 - 15|,|10 - 11|,|14 - 3|,|22 - 0|] = [15,1,11,22].

    Example 2:

    Input: nums = [1]

    Output: [0]

    Explanation: The array leftSum is [0] and the array rightSum is [0]. The array answer is [|0 - 0|] = [0].

    Constraints:

    • 1 <= nums.length <= 1000
    • 1 <= nums[i] <= 105
