## robottoorigin
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
There is a robot at position (0, 0) at 2D map.
|
||
|
|
|
||
|
|
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
|
||
|
|
- L - left
|
||
|
|
|
||
|
|
If the number of arguments is not 1, output `\n`.
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
```console
|
||
|
|
$> go build
|
||
|
|
$> ./main "UD"
|
||
|
|
true
|
||
|
|
$> ./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.
