Chef likes shopping, and especially he likes to buy oranges. But right now he is short of money. He has only k rubles. There are n oranges. The i-th one costs costi rubles and has weight equal to weighti. Chef wants to buy a set of oranges with the maximal possible weight. Please help him, and tell him this weight.
The first line of the input contains an integer T denoting the number of test cases. The first line of each test case contains two numbers n and k. The following n lines contain two numbers costi and weighti respectively.
For each test case, output a single line containing maximal weight among all the affordable sets of oranges.
- 1 ≤ T ≤ 250
- 1 ≤ n ≤ 10
- 1 ≤ k ≤ 100000000
- 1 ≤ weighti ≤ 100000000
- 1 ≤ costi ≤ 100000000
