SP31235 URJC2_F - Fractals

What is a fractal? According to wikipedia: A fractal is a mathematical set that exhibits a repeating pattern displayed at every scale. We are interested in developing a solution and create some fractals! This time we are interested on creating the ”H” fractal. The process to create it is as follows: • At scale 1, you have the ”H-H” string • At scale 2, you will copy the strings into four corners, each copy separated by a single space (row and column-wise) • You must connect the vertical copies with the pipe character or ’|’ and the horizontal copies with a dash character ’-’ between the pipes that connect the vertical copies (see the samples as clarification) • At scale 3 and further, you will repeat the step done on scale 2. Thus generating the fractal

You will receive a single integer N denoting the scale of the H fractal we want to generate.

You must output the generated H fractal as described above, in addition, the generated fractal MUST NOT have trailing spaces, this means that, after the last non-whitespace character of each row is printed, there must be nothing else but a newline written as output.
