Parallel lines

Input

Four integers are given: the coefficients $a$, $b$, $c$ of the line equation a x + b y + c = 0 and the value $r$. The absolute value of each input integer does not exceed $10000$.

Output

Print six numbers: the coefficients $a$, $b$, $c$ of the equations of two lines, each parallel to the given line and at a distance $r$ (r \neq 0) from it. Print three numbers per line. The coefficients must be printed with at least six decimal places of precision. The order of the lines does not matter.
