Karl has an array of integers. He wants to reduce the array until all remaining elements are equal. Determine the minimum number of elements to delete to reach his goal.
For example, if his array is , we see that he can delete the elements and leaving . He could also delete both twos and either the or the , but that would take deletions. The minimum number of deletions is .

Explanation
Array . If we delete and , all of the elements in the resulting array, , will be equal. Deleting these elements is minimal. Our only other options would be to delete elements to get an array of either or .
