CF1529B.Sifid and Strange Subsequences
Sifid and Strange Subsequences
A sequence is called strange, if the absolute difference between any pair of its elements is greater than or equal to the maximum element in the sequence. Formally speaking, it's strange if for every pair with , we have , where is the largest element of the sequence. In particular, any sequence of length at most is strange.
For example, the sequences and are strange, but is not, because .
Sifid has an array of integers. Sifid likes everything big, so among all the strange subsequences of , he wants to find the length of the longest one. Can you help him?
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 .
It is guaranteed that the sum of over all test cases doesn't exceed .
Output
For each test case output a single integer — the length of the longest strange subsequence of .
Note
In the first test case, one of the longest strange subsequences is
In the second test case, one of the longest strange subsequences is .
In the third test case, one of the longest strange subsequences is .
In the fourth test case, one of the longest strange subsequences is .
In the fifth test case, one of the longest strange subsequences is .
