question: private byte [ ] updateNoDictionaryStartAndEndKey ( byte [ ] key ) { if ( key . length == 0 ) { return key ; } ByteBuffer buffer = ByteBuffer . wrap ( key , 2 , key . length - 2 ) ; ByteBuffer output = ByteBuffer . allocate ( key . length - 2 ) ; short numberOfByteToStorLength = 2 ; for ( int i = 0 ; i < numberOfNoDictionaryColumn ; i ++ ) { output . putShort ( ( short ) ( buffer . getShort ( ) - numberOfByteToStorLength ) ) ; } while ( buffer . hasRemaining ( ) ) { output . put ( buffer . get ( ) ) ; } output . rewind ( ) ; return output . array ( ) ; }
target:  Below method will be used to update the no dictionary start and end key
