In middle school, Hawk often needs to solve quadratic equation problems. ### Input

The first line of the input contains an integer *n*(*n* < 1000). The next *n* lines contain *n*
equations, each equation is denoted by three double valued numbers, *a*, *b*, and *c*. The value of *a*
won't be zero.### Output

For each equation, output a line contains the solution. For quadratic equation, there may be two different values for
*X*, please output the smaller one firstly. Answers must be rounded to three digits after the decimal point. If the
equation has no solution, output "No solution!".
### Sample Input

### Sample Output

A quadratic equation, is an equation such as *aX ^{2}* +

Given the values of *a*, *b*, and *c*, would you please help Hawk determine the value of *X* ?
