CF1529A.Eshag Loves Big Arrays
Eshag Loves Big Arrays
Eshag has an array consisting of integers.
Eshag can perform the following operation any number of times: choose some subsequence of and delete every element from it which is strictly larger than , where is the average of the numbers in the chosen subsequence.
For example, if and Eshag applies the operation to the subsequence containing , , and , then he will delete those of these elements which are larger than , so after the operation, the array will become .
Your task is to find the maximum number of elements Eshag can delete from the array by applying the operation described above some number (maybe, zero) times.
A sequence is a subsequence of an array if can be obtained from by deletion of several (possibly, zero or all) elements.
Input
The first line contains an integer — the number of test cases. The description of the test cases follows.
The first line of each test case contains an integer — the length of the array .
The second line of each test case contains integers — the elements of the array .
Output
For each test case print a single integer — the maximum number of elements Eshag can delete from the array .
Note
Consider the first test case.
Initially .
In the first operation, Eshag can choose the subsequence containing , and , their average is equal to . So will be deleted.
After this .
In the second operation, Eshag can choose the subsequence containing the whole array , the average of all its elements is equal to . So and will be deleted.
After this .
In the second test case, Eshag can't delete any element.
