Write a program that takes two integers as arguments and displays the chess desk, in which white cells are represented by`' '` and black cells by`'#'`.

Write a program, that outputs `true` if robot ends up at the origin (0, 0) after a sequence of moves, otherwise `false`. `\n` should be in the end of line.
Sequence of moves is a string, which characters state for movement direction:
- U - up
- D - down
- R - right

### Usage
```console
$> go build
$> ./main "UD"
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./main "UD"
true
$> ./main "LL"
student@ubuntu:~/[[ROOT]]/test$ ./main "LL"
false
```
In first case, the robot moves up and the down. So, it returned back to its origin position.
In second example, the robot moves twice to the left. It is 2 positons left from its origin. So, program should output false.

- The function main declared needs to **also pass** the `Restrictions Checker`(illegal functions tester). It is advised for the student to just empty the function main after its own testings are done.
- Every other rules are obviously the same than for a `program`.
### Instructions:
Given an array of integers, return indices of the two numbers such that they add up to a specific target.

If there are more than one solution, return the first one.
If there are no solutions, return nil.
