Array
Hash Table
You are given an integer array nums. You need to ensure that the elements in the array are distinct. To achieve this, you can perform the following operation any number of times:
Note that an empty array is considered to have distinct elements. Return the minimum number of operations needed to make the elements in the array distinct.
Examples
Example 1
Input: nums = [1,2,3,4,2,3,3,5,7]
Output: 2
Explanation:
Therefore, the answer is 2.
Example 2
Input: nums = [4,5,6,4,4]
Output: 2
Explanation:
Therefore, the answer is 2.
Example 3
Input: nums = [6,7,8,9]
Output: 0
Explanation:
The array already contains distinct elements. Therefore, the answer is 0.
Constraints
1 <= nums.length <= 100
1 <= nums[i] <= 100
