时间限制 1000 ms   内存限制 32 MB

Now, here is a fuction:
  F(x) = 6 * x^7+8*x^6+7*x^3+5*x^2-y*x (0 <= x <=100)
Can you find the minimum value when x is between 0 and 100.
 

输入数据

The first line of the input contains an integer T(1<=T<=100) which means the number of test cases. Then T lines follow, each line has only one real numbers Y.(0 < Y <1e10)
 

输出数据

Just the minimum value (accurate up to 4 decimal places),when x is between 0 and 100.
