Data Compression algorithm
<p>I need an alogorihtm to store credit card data in reduced format [less memory].
For eg:-to store following number as 
12345665
12345777
12456666
12458888</p>

<p>as<br/>
12345 <br/> &nbsp;  &nbsp;&nbsp;    665 777<br/>
1245<br/>
  &nbsp;  &nbsp;&nbsp;6666 8888<br/>
Is there any algorithm to find out best storage group? </p>
