You are given an array of $$$n$$$ integers, and your task is to find three values (at distinct positions) whose sum is $$$x$$$.
InputThe 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:
- $$$3 \le n \le 5000$$$
- $$$1 \le x,a_i \le 10^9$$$
Print three integers: the positions of the values. If there are several solutions, you may print any of them. If there are no solutions, print $$$-1$$$.
