Epic Professor

Dr. Bahosain works as a professor of Computer Science at HU (Hadramout    University).

After grading his programming exam, he noticed that most of the students have failed. Since this is the last semester for him teaching in Yemen, Dr. Bahosain decided to give bonus marks to all students in a fair way.     He decided to give the same bonus marks to all students without making the mark of any student exceed 100.

Help Dr. Bahosain by finding the maximum possible number of students that will pass the course after adding the bonus marks.

A student will pass the course if his mark after adding the bonus marks is more than or equal to 50. Input

The first line of input contains an integer T (1 ≤ T ≤   1024) that represents the number of test cases.

The first line of each test case contains one integer N (1 ≤ N ≤ 100) that represents the number of students in Dr. Bahosain’s class.

The next line contains N space-separated integers between 0 and 100, each representing the initial mark of a student.

Output

For each test case, print a single line with the maximum number of students that will pass the course.
