1) Are $somerange and $otherange both limited to digits only ? ( My 
Answer : Don't think so ) 

2) Does the number of members of $somerange need to be equal to 
$otherange ( one to one mapping ) ? ( My Answer : Don't think so )

3) Can $somerange or $otherrange  have one member ? ( My Answer : Yes )
