**Python Implementation:**# Get the number of test cases from the user t = int ( raw_input () ) # Do until the number of test cases become "0" while ( t > 0 ) : # Create an empty list list = [] # Get space separated integers from the user (N, the number of students & K, ) n, k = map ( int, raw_input ().split () ) # Get the space separated N students as a string s = raw_input () # Split the string and store it in a list delimited by a space list = map ( int , s.split (' ') ) # If the sum of arrival time of the students in the list is less than "k" if ( sum ( i < = 0 for i in list ) < k ) : # Print YES print "YES" else : # Else Print NO print "NO" # Decrement number of test cases after evaluation of every test case t - = 1
