CF1642B.Power Walking
Power Walking
Sam is a kindergartener, and there are children in his group. He decided to create a team with some of his children to play "brawl:go 2".
Sam has power-ups, the -th has type . A child's strength is equal to the number of different types among power-ups he has.
For a team of size , Sam will distribute all power-ups to children in such a way that each of the children receives at least one power-up, and each power-up is given to someone.
For each integer from to , find the minimum sum of strengths of a team of children Sam can get.
Input
Each test contains multiple test cases. The first line contains a single integer () — the number of test cases. Description of the test cases follows.
The first line of each test case contains a single integer ().
The second line contains integers () — types of Sam's power-ups.
It is guaranteed that the sum of over all test cases does not exceed .
Output
For every test case print integers.
The -th integer should be equal to the minimum sum of strengths of children in the team of size that Sam can get.
Note
One of the ways to give power-ups to minimise the sum of strengths in the first test case:
One of the ways to give power-ups to minimise the sum of strengths in the second test case:
