3190. 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.

class Solution {
public:
    int minimumOperations(vector<int>& nums) {
        int res = 0;
        for(auto& x : nums) {
            if(x % 3) res++;
        }
        return res;
    }
};
