Print Pretty Hackerrank Solution in C++

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: A, B, and C, respectively.


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

Output Format

For each test case, print 3 lines containing the formatted A, B, and C, respectively. Each A, B, 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 lowercase letters.
  2. B: Print it to a scale of 2 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

100.345 2006.008 2331.41592653498
