Problem: You have $N$ items that you want to put them into a knapsack. Item $i$ has value $v_i$, weight $w_i$ and limitation $m_i$.

You want to find a subset of items to put such that:

* The total value of the items is as large as possible.
* The items have combined weight at most $W$, that is capacity of the knapsack.
* You can select at most $m_i$ items for $i$-th item.



Find the maximum total value of items in the knapsack.

Constraints

* $1 \le N \le 50$
* $1 \le v_i \le 50$
* $1 \le w_i \le 10^9$
* $1 \le m_i \le 10^9$
* $1 \le W \le 10^9$

Input


$N$ $W$
$v_1$ $w_1$ $m_1$
$v_2$ $w_2$ $m_2$
:
$v_N$ $w_N$ $m_N$


The first line consists of the integers $N$ and $W$. In the following $N$ lines, the value, weight and limitation of the $i$-th item are given.

Output

Print the maximum total values of the items in a line.
