## Lazy Salesman solution codechef

Ved is a salesman. He needs to earn at least WW rupees in NN days for his livelihood. However, on a given day ii (1iN1≤i≤N), he can only earn AiAi rupees by working on that day.

Ved, being a lazy salesman, wants to take as many holidays as possible. It is known that on a holiday, Ved does not work and thus does not earn anything. Help maximize the number of days on which Ved can take a holiday.

It is guaranteed that Ved can always earn at least WW rupees by working on all days.

### Input Format

• The first line contains a single integer TT – the number of test cases. Then the test cases follow.
• The first line of each test case contains two integers NN and WW – the size of the array AA and the money Ved has to earn in those NN days.
• The second line of each test case contains NN space-separated integers A1,A2,,ANA1,A2,…,AN denoting the money which Ved can earn on each day.

### Output Format

For each test case, output the maximum number of holidays Ved can take.

### Constraints

• 1T1001≤T≤100
• 1W100001≤W≤10000
• 1N1001≤N≤100
• 1Ai1001≤Ai≤100
• It is guaranteed that Ved can always earn at least WW rupees by working on all days.

### Explanation

Test case-1: Ved can work on 22-nd, 33-rd and 55-th day earning 2+6+3=112+6+3=11 rupees W≥W rupees. Thus he can take 22 holidays on the 11-st and the 44-th day.

Test case-2: Ved has to work on all days to earn W≥W rupees. Thus he can not take any holidays.

Test case-3: Ved can work on 22-nd day earning 1212 rupees W≥W rupees. Thus he can take holiday on the remaining days.
