Allocation

There are N houses for sale. The i-th house costs Ai dollars to buy. You have a budget of B dollars to spend.

What is the maximum number of houses you can buy?

The first line of the input gives the number of test cases, T. T test cases follow. Each test case begins with a single line containing the two integers N and B. The second line contains N integers. The i-th integer is Ai, the cost of the i-th house.

For each test case, output one line containing Case #x: y, where x is the test case number (starting from 1) and y is the maximum number of houses you can buy.

• 1 ≤ T ≤ 100.
• 1 ≤ B ≤ 105.
• 1 ≤ Ai ≤ 1000, for all i.

In Sample Case #1, you have a budget of 100 dollars. You can buy the 1st and 3rd houses for 20 + 40 = 60 dollars.

In Sample Case #2, you have a budget of 50 dollars. You can buy the 1st, 3rd and 4th houses for 30 + 10 + 10 = 50 dollars.

In Sample Case #3, you have a budget of 300 dollars. You cannot buy any houses (so the answer is 0).
