odd byte的意思|示意

Count the number of ones in each byte of the 8-byte block; if the number of ones is even, make it odd by setting the least significant bit to one.

统计8字节块中每字节中的1的个数，如果1的个数为偶数，那么就设置最低位为1使它成为奇数。

If the number of ones in a byte is already odd, you will set its least significant bit to a zero.

如果一个字节中1的个数已经为奇数，那么就将它的最低位设置为零。
