Y. Sum of Four Valuestime limit per test2 secondsmemory limit per test256 megabytesinputstandard inputoutputstandard output

You are given an array of $$$n$$$ integers, and your task is to find four values (at distinct positions) whose sum is $$$x$$$.

Input

The first input line has two integers $$$n$$$ and $$$x$$$: the array size and the target sum.

The second line has $$$n$$$ integers $$$a_1,a_2,\dots,a_n$$$: the array values.

Constraints:

  • $$$4 \le n \le 1000$$$
  • $$$1 \le x,a_i \le 10^9$$$
Output

Print four integers: the positions of the values. If there are several solutions, you may print any of them. If there are no solutions, print $$$-1$$$.

ExampleInput
8 15
3 2 5 8 1 3 2 3
Output
