* Check Loop Proof
1. (ac, bc) => (2ac, bc-ac) = (a, b) => (2a, b-a)
* a < b
1. (ac, bc+d) => (2ac, bc+d-ac) = (2ac, (b-a)c+d)
* a < b and 0 < d < c
1. (a, 2n-a) => (2a, 2n-2a) = (a, n-a)
* a < n
1. (x, y) will loop iff (x + y) % 2 == 1
* x and y are relative prime number

[level5/dodge-the-lasers] (1) Some of the text readme.txt are duplicated. (2) Though the input type is string, Java input example uses quotes for string instead of double quotation marks. (3) While expected output type is string, in the output example does not use quotes. So the readers can confuse the return type.
