Problem Statement of Minimum Elements to Add to Form a Given Sum

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]) = 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:

1 <= nums.length <= 105
1 <= limit <= 106
-limit <= nums[i] <= limit
-109 <= goal <= 109

Complexity Analysis

  • Time Complexity: O(n)
  • Space Complexity: O(1)
