HALCAND - Halum and Candies

no tags 

Halum has been elected as the captain of his school's football team. To celebrate this, he is going to throw a party. Halum bought candies of N different flavors for the party. There are ai number of candies of the ith flavor where (1 ≤ i ≤ N). To satisfy a guest he has to give him/her some positive number of candies of at least K different flavors. Otherwise the guest is not satisfied. Given this information now you have to find the maximum number of guests Halum can satisfy with the available candies.


First line of the input contains an integer T (1 ≤ T ≤ 200), denoting the number of test cases. T cases follow.
First line of each case contains two integers N and K (1 ≤ K ≤ N ≤ 1000). N space separated integers a1, a2… aN follow in the next line (0 ≤ ai ≤ 10^9). The ith of these integers ai denotes the number of candies of ith flavor (1 ≤ i ≤ N).


For each case print one line containing "Case X: Y" (without the quotes) where X is the case number starting from 1 and Y is an integer denoting the maximum number of guests who can be satisfied.
