Given the output of Racket's read-words/line function, which produces a list of lists. Each word is in a list, each group of words on a line is in a list, all within a list.<br><br>Any ideas on how to sort on the car (first element) of each list that corresponds to a line?<br>
<br>In other words, I want to sort lines based on the first word on a line. I want to keep the lines intact. <br>Thanks.<br>
