It's My Derivative
As an unnamed space agency endured the ridicule following their now-infamous metric/English unit conversion, they made a vow to never let that error happen again. Unfortunately, they over-hired poor college students with excellent metric/English unit conversion skills but not calculus skills. In fact, nobody at this agency can now remember how to calculate the derivative of a polynomial, let alone evaluate the derivative of a polynomial for a given value of x.
As any good government agency would do in this case, they've decided to outsource the task...to you. And not only do they want you to do the work, they want you to show how you did each step of your calculation so that they might re-learn the skill.
Input to this problem will begin with a line containing a single integer n indicating the number of input polynomials. Each of the following n lines contain:
For each polynomial in the input, output the following lines:
3 5 2x^7+x^2+3x-9 0 -5x^7+x^3+1 -3 5
POLYNOMIAL 1 2x^7+x^2+3x-9 14x^6+2x+3 14(5)^6+2(5)+3 218750+10+3 218763 POLYNOMIAL 2 -5x^7+x^3+1 -35x^6+3x^2 -35(0)^6+3(0)^2 0+0 0 POLYNOMIAL 3 5 0 0 0 0
