Short Problem Definition:
The professor is conducting a course on Discrete Mathematics to a class of N students. He is angry at the lack of their discipline, and he decides to cancel the class if there are less than K students present after the class starts.
Given the arrival time of each student, your task is to find out if the class gets cancelled or not.
time complexity is O(N);
space complexity is O(1)
Just count all students with arrival time <= 0.
