Simultaneous Equations 

Write a program that will solve a n by n system of simultaneous equations where the coefficients of the equations are complex numbers. (Recall that a complex number is an imaginary number of the form tex2html_wrap_inline38 , where a and b are real numbers.)


The input consists of tex2html_wrap_inline44 lines each containing n+1 complex numbers in the form (a,b). The tex2html_wrap_inline50 , complex number at line i is the coefficient of the tex2html_wrap_inline54 unknown in the tex2html_wrap_inline56 equation and the last complex number at line i represents the right-hand side of the tex2html_wrap_inline56 equation.


The output consists of n lines containing pairs of the form (a,b). The pair on line i of output represents the tex2html_wrap_inline56 root of the input system of equations. Each pair is to be printed in parenthesis with numbers accurately rounded to one digit to the right of the decimal point, as the sample below.

In case the input system of equations can not be uniquely solved, your program should produce the sentence ``No solution" as output.

Sample Input 1

(1,0) (2,0) (3,0) (14,0)
(2,0) (3,0) (4,0) (20,0)
(3,0) (4,0) (5,0) (26,0)

Sample Output 1


Sample Input 2

(1,0) (2,0) (3,0) (4,0)
(2,0) (4,0) (6,0) (8,0)
(3,0) (4,0) (5,0) (26,0)

Sample Output 2

No solution
