3190. Find Minimum Operations to Make All Elements Divisible by Three
Easy
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.
Example 1:
Input: nums = [1,2,3,4]
Output: 3
Explanation:
All array elements can be made divisible by 3 using 3 operations:
- Subtract 1 from 1.
- Add 1 to 2.
- Subtract 1 from 4.
Example 2:
Input: nums = [3,6,9]
Output: 0
Constraints:
1 <= nums.length <= 501 <= nums[i] <= 50
Solution
class Solution {
fun minimumOperations(nums: IntArray): Int {
var count = 0
for (i in nums.indices) {
if (nums[i] % 3 != 0) {
count++
}
}
return count
}
}
