Problem

Your manager gave you a text file with many lines of numbers to format and print. For each row of 3 space-separated doubles, format and print the numbers using the specifications in the Output Format section below.


Input Format :

The first line contains an integer, T, the number of test cases.
Each of the T subsequent lines describes a test case as 3 space-separated floating-point numbers: AB, and C, respectively.

Constraints :

  • 1 <= T <= 1000
  • Each number will fit into a double.

Output Format :

For each test case, print 3 lines containing the formatted AB, and C, respectively. Each AB, and C must be formatted as follows:

  1. A : Strip its decimal (i.e., truncate it) and print its hexadecimal representation (including the 0x prefix) in lower case letters.
  2. B : Print it to a scale 2 of decimal places, preceded by a + or  sign (indicating if it’s positive or negative), right justified, and left-padded with underscores so that the printed result is exactly 15 characters wide.
  3. C : Print it to a scale of exactly nine decimal places, expressed in scientific notation using upper case.

Sample Input :

1  
100.345 2006.008 2331.41592653498

Sample Output :

0x64             
_______+2006.01  
2.331415927E+03

Explanation :

For the first line of output, (100)10 -> (64)16 (in reverse, 6*16^1+4*16^0 = (100)10).
The second and third lines of output are formatted as described in the Output Format section.
