    2615 - Sum of Distances\.

    Medium

    You are given a 0-indexed integer array nums. There exists an array arr of length nums.length, where arr[i] is the sum of |i - j| over all j such that nums[j] == nums[i] and j != i. If there is no such j, set arr[i] to be 0.

    Return the array arr.

    Example 1:

    Input: nums = 1,3,1,1,2

    Output: 5,0,3,4,0

    Explanation:

    When i = 0, nums0 == nums2 and nums0 == nums3. Therefore, arr0 = |0 - 2| + |0 - 3| = 5.

    When i = 1, arr1 = 0 because there is no other index with value 3.

    When i = 2, nums2 == nums0 and nums2 == nums3. Therefore, arr2 = |2 - 0| + |2 - 3| = 3.

    When i = 3, nums3 == nums0 and nums3 == nums2. Therefore, arr3 = |3 - 0| + |3 - 2| = 4.

    When i = 4, arr4 = 0 because there is no other index with value 2.

    Example 2:

    Input: nums = 0,5,3

    Output: 0,0,0

    Explanation: Since each element in nums is distinct, arri = 0 for all i.

    Constraints:

    • <code>1 <= nums.length <= 10<sup>5</sup></code>

    • <code>0 <= numsi<= 10<sup>9</sup></code>
