Hackerrank Print Pretty Solution
Your manager gave you a text file with many lines of numbers to format and print. For each row of space-separated doubles, format and print the numbers using the specifications in the Output Format section below.
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.
- Each number will fit into a double.
For each test case, print lines containing the formatted , , and , respectively. Each , , and must be formatted as follows:
- : Strip its decimal (i.e., truncate it) and print its hexadecimal representation (including the prefix) in lower case letters.
- : 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.
- : Print it to a scale of exactly nine decimal places, expressed in scientific notation using upper case.

0x64 _______+2006.01 2.331415927E+03
For the first line of output, (in reverse, ).
The second and third lines of output are formatted as described in the Output Format section.
