# sortlines

Write a program called sortlines that reads one line at a time from the
standard input, and outputs the sequence of words in each line sorted in
lexicographical order. A word is a (maximal) contiguous sequence of alphabetic
characters as defined by the isalpha library function. The output sequence for
each line should be printed on a single line with each word separated by one
space. An input line is guaranteed to be at most 1000 characters.
