1785 - Minimum Elements to Add to Form a Given Sum.Medium
You are given an integer array
nums
and two integerslimit
andgoal
. The arraynums
has an interesting property thatabs(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 thatabs(nums[i]) <= limit
.Note that
abs(x)
equalsx
ifx >= 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
