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:

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