Takahashi will participate in a programming contest, which lasts for $T$ minutes and presents $N$ problems. With his extrasensory perception, he already knows that it will take $A_i$ minutes to solve the $i$\-th problem. He will choose zero or more problems to solve from the $N$ problems so that it takes him no longer than $T$ minutes in total to solve them. Find the longest possible time it takes him to solve his choice of problems. ## Constraints * All values in input are integers. * $1 \le N \le 40$ * $1 \le T \le 10^9$ * $1 \le A_i \le 10^9$ ## Input Input is given from Standard Input in the following format: $N$ $T$ $A_1$ $\dots$ $A_N$ [samples]
Samples
Input #1
5 17
2 3 5 7 11
Output #1
17

If he chooses the $1$\-st, $2$\-nd, $3$\-rd, and $4$\-th problems, it takes him $2+3+5+7=17$ minutes in total to solve them, which is the longest possible time not exceeding $T=17$ minutes.
Input #2
6 100
1 2 7 5 8 10
Output #2
33

It is optimal to solve all the problems.
Input #3
6 100
101 102 103 104 105 106
Output #3

Output #4
273555143

If he chooses the $2$\-nd, $3$\-rd, and $7$\-th problems, it takes him $273555143$ minutes in total to solve them.
