Text justification problem

Given some strings and a width of a screen. How do you align the strings so that they do not exceed the width of the screen. Or in other words where do you put line breaks between strings so that it looks as pretty as possible or text looks as aligned as possible.

```Input : { "Abcdef", "Xyz", "Likes", "To", "Code" } Output : Abcdef Xyz Likes To Code ```

```package com.omt.learn.algo;

printText(a, width);
