question: public static int crc ( byte [ ] bytes , int start , int end , int initialValue ) { for ( int i = start ; i < end ; i ++ ) { initialValue = ( initialValue << 8 ) ^ CRC32_BYTES_MSBF [ ( ( initialValue > > > 24 ) ^ ( bytes [ i ] & 0xFF ) ) & 0xFF ] ; } return initialValue ; }
target:  Returns the result of updating a CRC with the specified bytes in a "most significant bit first" order.
