We are building a word processor and we would like to implement a "reflow" functionality that full-justifies text. Given a maximum line width and an array containing lines of text, re-flow the text to fit the new width. Each line should be the exact specified width. If any line is too short, insert - (as stand-ins for spaces) between words as equally as possible until it fits. Example input 12 It was the best of times it was the worst of times Example output It--was--the best------of times-it-was the-worst-of
