51 - Bytes Arrays

Fixed-size Byte Arrays: The value types bytes1, bytes2, bytes3, …, bytes32 hold a sequence of bytes from one to up to 32. The type byte[] is an array of bytes, but due to padding rules, it wastes 31 bytes of space for each element (except in storage). It is better to use the bytes type instead.
