453. Minimum Moves to Equal Array Elements
Medium
Given an integer array
nums of size n, return the minimum number of moves required to make all array elements equal.In one move, you can increment
n - 1 elements of the array by 1.Example 1:
Input: nums = [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]
Example 2:
Input: nums = [1,1,1]
Output: 0
Constraints:
n == nums.length1 <= nums.length <= 10^5-10^9 <= nums[i] <= 10^9- The answer is guaranteed to fit in a 32-bit integer.
func minMoves(nums []int) int {
// sum - length*min
minv := nums[0]
sum := 0
for _, n := range nums {
sum += n
minv = min(minv, n)
}
return sum -len(nums)*minv
}
func min(a, b int) int {
if a < b { return a }
return b
}
