【LeetCode】453. Minimum Moves to Equal Array Elements

题目描述:

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]

代码实现:

class Solution {
public:
    int minMoves(vector<int>& nums) {
        int min=INT_MAX;
        int sum=0;
        for(int num:nums){
            min=min<num?min:num;
        }
        for(int num:nums){
            sum+=(num-min);
        }
        return sum;
    }
};
