find-minimum-operations-to-make-all-elements-divisible-by-three

You are given an integer array nums. In one operation, you can add or subtract 1 from any element of nums.

Return the minimum number of operations to make all elements of nums divisible by 3.

Example 1:

Input: nums = [1,2,3,4]

Output: 3

Explanation:

All array elements can be made divisible by 3 using 3 operations:

• Subtract 1 from 1.


• Add 1 to 2.


• Subtract 1 from 4.

Example 2:

Input: nums = [3,6,9]

Output: 0

Constraints:

• 1 <= nums.length <= 50


• 1 <= nums[i] <= 50
