Input is of format x;y instead of y;x, so 0;0 0;0 0;1 1;1 gives

2|0
1|1

instead of

2|0
1|1

.

FixedTests("0;0 0;0 0;1 1;1",0)
Test Failed
Expected and actual are both <System.Char[3]>
Values differ at index [2]
Expected: 'e'
But was: 's'

Why it should be "east"? If array contains element at position 0;1 that means 0;0 will be not visible from "east".What am i doing wrong or what i don't understand?
