Binary operators:
1. Invert operation ~
~a
For the binary of a, change 1 to 0 and 0 to 1
2. Left shift operator <<
a<<2
Shift the binary of a to the left by two bits, the vacant bits on the right are filled with 0, and the left overflow bits are discarded directly
3. Right shift operator >>
a>>2
Shift the binary of a to the right by two bits, the vacant bits on the left are filled with 0, and the bits removed on the right are discarded
4. Bitwise XOR operator ^
a^b
For the binary of a and b, if the same bit is the same, it is 0, and if it is different, it is 1
5. Bitwise AND operator &
a&b
For the binary of a and b, if the same bit is 1, it is 1, otherwise it is 0
6. Bitwise OR operator |
a|b
For the binary of a and b, if one of the same bits is 1, it is 1, otherwise it is 0
