(Java) LeetCode 453. Minimum Moves to Equal Array Elements —— 最小移动次数使数组元素相等

Given a non-empty integer array of size n, find the minimum number of moves required to make all array elements equal, where a move is incrementing n - 1 elements by 1.

Example:

Input:
[1,2,3]

Output:
3

Explanation:
Only three moves are needed (remember each move increments two elements):

[1,2,3]  =>  [2,3,3]  =>  [3,4,3]  =>  [4,4,4]

class Solution {
    public int minMoves(int[] nums) {
        int min = nums[0], sum = 0;
        for (int num : nums) {
            if (num < min)
                min = num;
            sum += num;
        }
        return sum - nums.length * min;
    }
}
