Each line following the command will be formatted such that each line has exactly maxwidth characters and is fully (left and right) justified. The original whitespace in the input text need not necessarily be preserved (i.e., single or multiple spaces would be used to separate words in the output). You should pack your words in a greedy approach; that is, pack as many words as you can in each line. Pad extra spaces ' ' when necessary so that each line has exactly maxwidth characters. Extra spaces between words should be distributed as evenly as possible. If the number of spaces on a line do not divide evenly between words, the empty slots on the left will be assigned more spaces than the slots on the right.
