# Queen Attack
|
||
|
|
|
||
|
|
Welcome to Queen Attack on Exercism's C Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Given the position of two queens on a chess board, indicate whether or not they are positioned so that they can attack each other.
|
||
|
|
|
||
|
|
In the game of chess, a queen can attack pieces which are on the same row, column, or diagonal.
|
||
|
|
|
||
|
|
A chessboard can be represented by an 8 by 8 array.
|
||
|
|
|
||
|
|
So if you are told the white queen is at `c5` (zero-indexed at column 2, row 3) and the black queen at `f2` (zero-indexed at column 5, row 6), then you know that the set-up is like so:
|
||
|
|
|
||
|
|
```text
|
||
|
|
a b c d e f g h
|
||
|
|
8 _ _ _ _ _ _ _ _ 8
|
||
|
|
7 _ _ _ _ _ _ _ _ 7
|
||
|
|
6 _ _ _ _ _ _ _ _ 6
|
||
|
|
5 _ _ W _ _ _ _ _ 5
|
||
|
|
4 _ _ _ _ _ _ _ _ 4
|
||
|
|
3 _ _ _ _ _ _ _ _ 3
|
||
|
|
2 _ _ _ _ _ B _ _ 2
|
||
|
|
1 _ _ _ _ _ _ _ _ 1
|
||
|
|
a b c d e f g h
|
||
|
|
```
|
||
|
|
|
||
|
|
You are also able to answer whether the queens can attack each other.
|
||
|
|
In this case, that answer would be yes, they can, because both pieces share a diagonal.
