Input Format

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

Constraints

• Each number will fit into a double.

Output Format

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

1. : Strip its decimal (i.e., truncate it) and print its hexadecimal representation (including the  prefix) in lower case letters.
2. : Print it to a scale 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  characters wide.
3. : Print it to a scale of exactly nine decimal places, expressed in scientific notation using upper case.
