Text Formatting Text Formatting
Elementary+
English RU

You are given a long line (a monospace font), and you have to break the line in order to respect a given width. Then you have to format the text according to the given style: 'l' means you have to align the text to the l eft, 'c' for c enter, 'r' for r ight, and 'j' means you have to j ustify the text. Finally, the lines of the output shouldn’t end with a whitespace.

If you have to put 2 * n + 1 spaces around a line in order to center it, then put n spaces before, not n + 1.

The justification rules:

  • Since we can't always put the same number of spaces between words in a line, put big blocks of spaces first. For example: X---X---X--X--X--X when you have to put 12 spaces in 5 gaps: 3-3-2-2-2.
  • Don't justify the last line of a text.

You won't have to consider splitting a word into two parts because the given widths are big enough.

Input: A text (string), width (integer) and style (string).

Output: The formatted text (string).

Examples:

text = "Hi, my name is Alex and I am 18 years old."

text_formatting(text, 20, 'l') == \
"""Hi, my name is Alex
and I am 18 years
old."""

text_formatting(text, 20, 'c') == \
"""Hi, my name is Alex
 and I am 18 years
        old."""

text_formatting(text, 20, 'r') == \
""" Hi, my name is Alex
   and I am 18 years
                old."""

text_formatting(text, 20, 'j') == \
"""Hi,  my name is Alex
and  I  am  18 years
old."""

Preconditions:

  • all(len(word) <= width for word in text.split())
  • '\n' not in text
  • style in ('l', 'c', 'r', 'j')
  • 0 < len(text) <= 1000
