Problem Statement |
| | You have a page of text that is nicely formatted in the usual fashion (like this text), but you wanted it formatted in two columns, like a magazine. Given a String[] text, and an int width, return a String[] which is the same text but formatted such that every element contains as many words as possible without being more than width characters long. Begin by putting as many words as possible in the first line of the first column without using more than width characters, then continue this for each subsequent line. The elements of the return value should be organized such that every pair of elements corresponds to one line of text, spread over two columns. Thus element 2*i and 2*i+1 (with i starting at 0) of the output will represent the i-th line of the first and second columns, respectively. If the last line of the second column has no text, do not include it as part of the return value (see example 0). Do not hyphenate words to fit them on two lines. Also, there should only be a single space between adjacent words, and there should be no leading or trailing spaces in the lines. A 'word' is a sequence of non-space characters that does not have non-space characters immediately before or after it. Punctuation marks should be treated the same as other characters. For example, "Hello,Fred", "Hello,I'mFred", and "...!?!?" are all considered to be single words, and should not be broken apart in any way.
For example, if text={"This text is now ","in two columns."} and width=7, the output would be {"This", "two", "text is", "columns.", "now in"}. Making the first element of the return value the first line of the first column, the next element the first line of the second column, and then continuing in the same way for subsequent rows, the text looks like this:
"This" "two"
"text is" "columns."
"now in"

Definition |
| | | Class: | TextEditor | | Method: | twoColumn | | Parameters: | String[], int | | Returns: | String[] | | Method signature: | String[] twoColumn(String[] text, int width) | | (be sure your method is public) |
|
| |
|
| |
Constraints |
| - | text will contain between 1 and 50 elements, inclusive. |
| - | width will contain between 1 and 50, inclusive. |
| - | Each element of text will be between 1 and 50 characters, inclusive. |
| - | Each element of text will contain only upper and lower-case letters ('a'-'z','A'-'Z'), digits ('0'-'9'), spaces, and the characters ".,;:?!". Quotes and parentheses in all cases are for clarity only. |
| - | No element of text will contain a string of non-space characters longer than width. |

Examples |
| 0) | |
| | {"The quick brown fox jumps over the lazy dog. "} | 7 |
| Returns:
{ "The",
"over",
"quick",
"the",
"brown",
"lazy",
"fox",
"dog.",
"jumps" } | Only one word can fit per line. Making two columns with this output looks like this:
"The", "over",
"quick","the",
"brown","lazy",
"fox", "dog.",
"jumps"
