Lucy is taking math analysis classes in her school. She always has a lot of homework and she always spends a considerable amount of time in order to do it, but today she had completely forgotten about it for some reason. So, please, help her!
Lucy asks you to solve to following problem: calculate the following:
Output the result till the D-th digit after the decimal point. We're asking you to output truncated result, but not rounded!
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows.
Each test is described by a line of four numbers - a, p, q and D respectively. a, p, q will be given with exactly two digits after the decimal point.
For each test case, output a single line containing the answer to the corresponding test case (with D digits after the decimal point).
Input: 3 0.62 2.71 3.14 42 0.91 4.70 6.67 18 0.01 9.81 8.63 66 Output: 17.903573407202216066481994459833795013850415 796.867901234567901234 0.187143148658300173451688603203754718906234057749209264360779512294
In all the test cases, 0.01 <= a < 1.00, 0.00 <= p <= 10.00, 0.00 <= q <= 10.00
Output will not exceed 1 MB
Subtask 1 (31 point): T = 100000, 5 <= D <= 7, 0.01 <= a <= 0.50
Subtask 2 (29 points): T = 100, 50 <= D <= 100
Subtask 3 (15 points): T = 10000, 50 <= D <= 100
Subtask 4 (25 points): 10 <= T <= 100, 1 <= D <= 100000
