Easy

18

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] <= 10`
