6 tips you must know to master bit operation

Bit operation is useful in algorithms and can be much faster than arithmetic operations.

Here are 6 tips you must know to master it:

1. Before learning bit operation, you should know how decimal converts to binary and how binary turns to decimal. Here is a simple calculation method.

2. Shift Arithmetic Left <<

Shift arithmetic left is to move all the binary to the left.

3. Shift Arithmetic Right >>

The bitwise right shift moves all the binary digits to the right and removes the extra left digit.

4. Bitwise And

Each bit is 1, and the result is 1

5. Bitwise Or

One of bit is 1, and the result is 1

6. Bitwise XOR

Each bit is different, and the result is 1

From the below code, we can find that the bitwise XOR is the not carry addition.
