You are working in a team that writes Incredibly Customizable Programming Codewriter (ICPC) which is basically a text editor with bells and whistles. You are working on a module that takes a piece of code containing some definitions or other tabular information and aligns each column on a fixed vertical position, while keeping the resulting code as short as possible, making sure that only whitespaces that are absolutely required stay in the code. So, that the first words on each line are printed at position ; the second words on each line are printed at the minimal possible position , such that all first words end at or before position ; the third words on each line are printed at the minimal possible position , such that all second words end at or before position , etc.
Input Specification
The input contains one or more lines of the code up to the end of file. All lines (including the last one) are terminated by a standard end-of-line sequence. Each line contains at least one word, each word is to characters long (inclusive). Words are separated by one or more spaces. Lines of the code can have both leading and trailing spaces. Each line in the input is at most characters long. There are at most lines in the input.
Output Specification
Write to the output the reformatted, aligned code that consists of the same number of lines, with the same words in the same order, without trailing and leading spaces, separated by one or more spaces such that the -th word on each line starts at the same position .
The _
character in the example below denotes a space character in the
actual input (ASCII code ).
Sample Input
__start:__integer;____//_begins_here
stop:_integer;_//__ends_here__
_s:__string;___
c:___char;_//_temp_
Sample Output
start:_integer;_//_begins_here
stop:__integer;_//_ends___here
s:_____string;
c:_____char;____//_temp
