Adding `1`

to `n - 1`

elements is the same as subtracting `1`

from one element, w.r.t goal of making the elements in the array equal.

So, best way to do this is make all the elements in the array equal to the `min`

element.

`sum(array) - n * minimum`

```
public class Solution {
public int minMoves(int[] nums) {
if (nums.length == 0) return 0;
int min = nums[0];
for (int n : nums) min = Math.min(min, n);
int res = 0;
for (int n : nums) res += n - min;
return res;
}
}
```
