    1785 - Minimum Elements to Add to Form a Given Sum.

    Medium

    You are given an integer array nums and two integers limit and goal. The array nums has an interesting property that abs(nums[i]) <= limit.

    Return the minimum number of elements you need to add to make the sum of the array equal to goal. The array must maintain its property that abs(nums[i]) <= limit.

    Note that abs(x) equals x if x >= 0, and -x otherwise.

    Example 1:

    Input: nums = 1,-1,1, limit = 3, goal = -4

    Output: 2

    Explanation: You can add -2 and -3, then the sum of the array will be 1 - 1 + 1 - 2 - 3 = -4.

    Example 2:

    Input: nums = 1,-10,9,1, limit = 100, goal = 0

    Output: 1

    Constraints:

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

    • <code>1 <= limit <= 10<sup>6</sup></code>

    • -limit &lt;= nums[i] &lt;= limit

    • <code>-10<sup>9</sup><= goal <= 10<sup>9</sup></code>
