Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

standard inputoutput

standard outputPolycarp is choosing three problems for creating a programming test. Totally he has $$$n$$$ problems in his list. The complexity of the $$$i$$$-th problem equals $$$r_i$$$. All problems are numerated from $$$1$$$ to $$$n$$$.

Help Polycarp to choose such three problems $$$a$$$, $$$b$$$ and $$$c$$$, so that the complexity of the first problem strictly less than the complexity of second problem and the complexity of the second problem is strictly less than the complexity of the third problem. So, for chosen problems $$$a$$$, $$$b$$$ and $$$c$$$ it should be true that $$$r_a < r_b < r_c$$$.

If Polycarp can choose three problems in different ways, you can print any of them.

Input

The first line of the input contains one integer $$$n$$$ ($$$3 \le n \le 3000$$$) — the number of problems in Polycarp's list.

The second line of the input contains $$$n$$$ integers $$$r_1, r_2, \dots, r_n$$$ ($$$1 \le r_i \le 10^9$$$), where $$$r_i$$$ is the complexity of the $$$i$$$-th problem.

Output

If Polycarp has no ways to choose three problems, you should print three numbers -1. Ih there is a way to choose them, you should print three different integers $$$a, b, c$$$ ($$$1 \le a, b, c \le n$$$), where $$$a$$$ is the number of the first chosen problem, $$$b$$$ is the number of the second chosen problem and $$$c$$$ is the number of the third chosen problem.
