Line 5:
An alignment is a notation used to describe the operations used to turn a string into an other. At some point in the strings, the minus character ('-') is placed in order to signify that a character must be added at this very place. For instance, an alignment between the words 'place' and 'palace' is:
 
<pre>P-LACE
P-LACE
PALACE</pre>
</pre>
 
 
For this task, write a function that shows the alignment of two strings for the corresponding levenshtein distance. As an example, use the words "rosettacode" and "raisethysword".

As an example, use the words "rosettacode" and "raisethysword".
 
You can either implement an algorithm, or use a dedicated library (thus showing us how it is named in your language).
