Angry Professor - Hackerrank

https://www.hackerrank.com/challenges/angry-professor

A Discrete Mathematics professor has a class of N$N$ students. Frustrated with their lack of discipline, he decides to cancel class if fewer than K$K$ students are present when class starts.

Given the arrival time of each student, determine if the class is canceled.

The first line of input contains T$T$, the number of test cases.

Each test case consists of two lines. The first line has two space-separated integers, N$N$ (students in the class) and K$K$ (the cancelation threshold). 
The second line contains N$N$ space-separated integers (a1,a2,…,aN$a_1,a_2,\dots ,a_N$) describing the arrival times for each student.

Note: Non-positive arrival times (ai≤0$a_i\le 0$) indicate the student arrived early or on time; positive arrival times (ai>0$a_i>0$) indicate the student arrived ai$a_i$ minutes late.
